Didn't notices this. Shall read it thru again.

I am not so sure that Semi noise is "True" random noise.

Semi devices are characterized at the atomic level as having quantum states, therefore

not continuous, finite.

Thermal Noise      - http://physics.stackexchange.com/questions/35911/is-thermal-noise-quantum-random

- http://en.wikipedia.org/wiki/Johnson%E2%80%93Nyquist_noise            Nearly, but not totally

Shot Noise             - Maybe closest to white, but not a semi phenomina

Popcorn Noise      - Process based noise.

Flicker                      - Process dependent.

Hi Dana Thank usefull info and links Kamil P.S. randomity and chaos is very interesting theme

There is also a library function "int rand(void)" in ICC compiler. Refer "C Language Compiler User Guide" for details.
• ###### 19. Re: True random generator help

Those are all psudo random generator. not true random number generator

Dima, when you look at the first posts in this thread you will find links to explanations of "True" and "Pseudo" random generators. Since (as far as I understand) the order was to create a "True" generator there is the need to connect a PSoC to some random physical process like noise of radiation or thermal noise (which will not always be white noise afak)

(CAN YOU HERE ME? or too much noise?? )

@dana,

Interesting paper.

Tks

• ###### 23. Re: True random generator help

Yes this is very interresting paper !

Many thanks

If your looking for an ANALOG random noise generator, see the attached article draft, it will be published in a few weeks. If your are looking for a digital random number generator, you can simply set up a timer and read the PRS output. How random do you need? A 32 bit PRS clocked at 1 MHz repeats every 1.19 hours, and you can use more blocks to make it longer. 40 bits gets 305 hour repeats. ---- Dennis
