Use of decimate and down-mixer:
Down-mixer allows us to move across frequency range down-sampling.
What is decimation?
"a technique for reducing the number of samples in a discrete-time signal."
Play deck window - advanced features: high pass and low pass filters, use of shift for demodulation.
3] ITC/EVP ref:
EM related: http://members.tripod.com/:/Article1.htm
Simple design based on Analog Device's AD8313 chip, providing visual display of broadband signal strength and audio level output of demodulated signal.
The circuit detects, demodulates the amplitude and amplifies high frequency electromagnetic emissions (100 MHz to 2.5 GHz approx) for audio frequency output. The main component is the Analog Devices AD8313 IC: RF logarithmic detector and controller, whose output is further amplified by the TL082 op-amp.

Layout: 
In GNU Emacs:
1] M-x octave mode
2] Use C-c TAB C-l to evaluate the last Octave statement (eg. help)
[also used to start the inferior Octave process which we can interact with in the other window/frame.]
3] Ctrl-up-arrow/down-arrow to cycle through history at Octave prompt.
4] Opening a file as raw 8 bit character (unsigned) and plotting a histogram of values:
myfile = fopen("testrnd_delay_none", "r+")
x =fread(myfile, "uchar");
hist(x)
hist(x(1:50))
plot(x)
fclose(myfile)
3] Help/info issues:
At first there were some problems with help/GNU info in Emacs with Octave. These were solved with:
(require 'octave-hlp) (in Emacs) and apt-get install octave3.0-info

2] Transparent version control using SVNAutoversioning and davfs// simple recipe:
In httpd.conf: <Location /repos> DAV svn SVNPath /root/svnrepo SVNAutoversioning on </Location> Making sure that we link: ln -s ../mods-available/dav_fs.load . and other dav stuff into mods-enabled // restart apache and test access in browser 127.0.0.1/repos/ Some play with repo permissions and finally: mount.davfs -o uid=xxxxx,gid=users,rw,no_netdev http://127.0.0.1/repos/ /dav
Code updated (bug in serial code produced extra carriage returns 0x0d.

and a different scheme for unbiasing (for the moment without XOR of alternate ones and zeroes).
Using baudline for quick histogram and raw file analysis:

Entropy = 7.997799 bits per byte. Optimum compression would reduce the size of this 84058 byte file by 0 percent. Chi square distribution for 84058 samples is 257.79, and randomly would exceed this value 43.93 percent of the times. Arithmetic mean value of data bytes is 127.5481 (127.5 = random). Monte Carlo value for Pi is 3.127132558 (error 0.46 percent). Serial correlation coefficient is -0.000152 (totally uncorrelated = 0.0).

Notes:
Reverse-biasing of a 2n3904 transistor across 20V (produced by MAX232), generates avalanche noise which is amplified by one more transistor and further amplified and transformed into a square wave by Schmitt trigger 74HC14. This signal is sampled as a 1 or 0 by the digital input of an ATmega8. The sample is unbiased after Von Neuman and accumulated towards a single byte which is transmitted to the PC by way of USB/serial interface (FT232RL).

2] Jack and cat?
To be able to cat to each channel of soundcard:
PD: perhaps use piperead~ and pipewrite~ with jackd and adc~/dac~ 1 2 usw. TO TEST
Jack: apt-get install jack-tools from Rohan Drape: use perhaps of jack.plumbing
alsaplayer can be used to play to a certain channel but doesn't accept STDIN
ecasound:

The ATmega128 at: http://library.oshec.org/library/avr.lib
62256: http://library.oshec.org/library/memory-hitachi.lib
2] Making and connecting buses:
From Kicad online help:
In fact, due to the repetition command (Insert key), connections can be very quickly made in the following way, if component pins are aligned in increasing order (a common case in practice on components such as memories, microprocessors…):
Place the first label (for example PCA0)
Use the repetition command as much as needed to place members. EESchema will automatically create the next labels (PCA1, PCA2…) vertically aligned, theorycally on the position of the other pins.
Draw the wire under the first label. Then use the repetition command to place the other wires under the labels.
If needed, place the bus entries by the same way (Place the first entry, then use the repetition command).
Which boils down to:
1] Using foggy/tracing paper (Artoz Perga Pastel) gives better results than Folie 3562 Overhead transparency when printed with laser printer (600 dpi) though latter can be used if fill in gaps. (SMD/T fine with five minutes below).
2] Warm-up UV lights (see pcb below) for two minutes. Switch off briefly and line up with ink facing PCB (in dim daylight is fine). Expose tracing paper for five minutes/ overhead transparency for two and a half to three minutes (heavy books on scanner/UV box lid). Develop for three to five in the Natriumhydroxid (Sodium Hydroxide I think (10g in 1000ml)). Wash in cold water. (above in dull light).
3] Now etching in Natriumpersulphat (Sodium Persulphate) which is faster, cleaner and more accurate. Dissolve 120g in 600ml water. Heat up in bath to 40 degrees or more. Etch board for around 15 minutes until copper vanishes - agitating as much as possible. Wash and dry boards and save solvent removal of UV paint until just before soldering.
1] When we export by way of plot option and then ps2pdf and then into GIMP the image is too small. We need to scale X and Y in the plot option to 1.08.
2] To test boards with three options:
a) latest foggy transparency paper
b) clear OHP film
c) foggy as diffuser and then with clear OHP film
... for SMT, double-sided, new VLF design, spectral boards (inc. TV transmitter)
Added data radio (encoder and decoder), osctrans/oscdump (making use of libOSC, dumpOSC and sendOSC) and devdisplay as an xxxxx module to pure:dyne:
https://devel.goto10.org/puredyne
see software for descriptions of these commandline applications.
Module is:
http://1010.co.uk/xxxxx.dyne (to add to a pure:dyne distribution mount -o loop the current iso, copy to a new directory the resulting directories, insert xxxxx.dyne into dyne/modules, mkisofs using the invocation of:
https://devel.goto10.org/puredyne/wiki/ - or just add to docked system)
Module was created at speed and with few problems (Fedora Core system unusable for dev system due to LVM/GRUB mismatch).
1] Set up development system according to:
https://devel.goto10.org/puredyne/wiki/
except refs to: mkdir cd /vol/hd1/puredyne-svn
and:
ln -s /vol/hd1/puredyne-svn/puredyne $DYNE_SYS_MNT/SDK/modules/pure
don't make sense but make the repository on the mounted drive and link accordingly to the right path
2] Create a new module and add software to the module according to:
https://devel.goto10.org/puredyne/wiki/
3] Create the ISO WITHOUT using dynesdk mkiso but manually using mount and mkisofs by way of customiso link above
4] xxxxx ISO is at: http://plot.bek.no/~crash2005/puredynexxxxx_april2007.iso
5] Module will be updated soon for xxxxx workflow: ATmega8/Atmel development apps, GNU Emacs extensions, promiscuOS, cur-rme usw.

3) Design is placed with ink in contact with photo-sensitive (fotopositiv) PCB material from Conrad. Plastic protection is first peeled off - all of this process in near darkness. PCB is exposed for three minutes to UV light using a darkroom timer to time this.
4) Pre-mixed developer/entwickler (Natriumhydroxid from Conrad - 10g to 1 litre of 20 degree C water. Development time varies from three to five minutes as developer ages.
5) After development rinse in cold water and develop in etch solution (see: simple_pcb_guide for this part of the process.

6] in my .emacs:
(add-to-list 'load-path "/root/SuperCollider3/linux/scel/el") (require 'sclang)
7] in my .bash_profile:
export SC_LIB_DIR=/usr/share/SuperCollider/SCClassLibrary export SC_JACK_DEFAULT_INPUTS="alsa_pcm:capture_1,alsa_pcm:capture_2" export SC_JACK_DEFAULT_OUTPUTS="alsa_pcm:playback_1,alsa_pcm:playback_2" export SC_SYNTHDEF_PATH="./synthdefs"
8] start Emacs with emacs -sclang
9] sclang should be initialised and we see:
// ===================================================================== // SuperCollider Workspace // =====================================================================
in the buffer and:
----:---F1 *SCLang:Workspace* All L5 (SCLang)------------------------------------
in the minibuffer. In this mode we can get help with C-x C-h m
10] change [ C-x C-b ] to scratch buffer and evaluate (C-x C-e after each line - the following):
(sclang-start)
(sclang-eval-expression "EvalListener.init")
(sclang-server-boot)
first may not be necessary but...
11] switch back to our Sclang buffer and to test:
s = Server.local;
SynthDef("mysynth", { Out.ar(0, PinkNoise.ar(0.25)) }).play(s);
s.freeAll
Using C-c C-c to evaluate each line in turn...
