Hi All,
I want to generate a true **random** **number** in Actel ProAsic3 FPGA development board which operates at 48 MHz. I tried to implement it using ring oscillators (RO) and used the system clock i.e. 48 MHz as sampling frequency. As the sampling period is around 48 MHz => 21 ns, the RO period should at least be double the sampling frequency, i.e.

I am trying to generate TRUE **random** **number**s on Kintex-7. I am following the paper published by Xilinx, where a ring oscillator is used for **random** **number** generation and LHCA has been used as a scrambler.
BUT, whenever I capture 11 Mega bytes of data (True **random** **number**s) and pass them (...)

Hi,
look for "Pseudo **random** **number** **generator**" using shift registers with feedback.
I´ve used it with AVRs and assembler, but not on PICs.

Hi All
I have a problem to NOISE Analysis in HSPICE 2013.
I am working on True **random** **number** **generator** based on Metastability.
I have to simulate a circuit in HSPICE and I have to analysis the Noise.
Can any one to help me?

Hello,
I design an inductorless Chua circuit based on the design found in
and by replacing the LMC6482AIN opamp by TL081
The circuit works but when I tried to connect the output with comparator (open loop TL0821 opamp or LM311) the output signal was vanished.
I tried to couple the two

Hi Guys.
Recently, I'm getting interested in the PRN **generator** Using Linear Feedback Shifting Register(LFSR).
If Low Power Performance is desired, which Logic Type and clock strategy are preferred.

I am using a Bernoulii Binary **generator** to generate my data signal for a Direct sequence spread spectrum model I am designing on SIMULINK. The specifications of the **generator** block is as follows :
Probability of zero : 0.5
Initial seed : 61 ( **random** **number** )
sample time : 0.6
Frame based outputs
Samples per frame : (...)

@Trickedeasy
Whether the seed are initialised to a particular **number** or left uninitialised, for both cases, same sequence of **random** **number** are generated
I think this is not true for a LFSR **generator**. probably you could not load your LFSR correctly or mot simulating enough time.
I need **random** seed values (...)

Hi all,
Can any body plz give me code to generate 4 digit **random** **number** which should not be repeated if appear once until all 9998 combinations. Code should run in KEIL for ARM. I wrote one with '**random**ize ()' and **random** function which is giving an error in KEIL.
Plz guide.

The Monte Carlo process isn't truly **random**. It uses a pseudo **random** **number** **generator** based on a seed value. If you don't change the seed you will get identical results from two groups of Monte Carlo runs. I have never experimented with netlist order but it seems reasonable that changing that will change the results. The (...)

do u have the matlab code for gaussian noise generation without wgn or awgn functions.....i would like to generate statistical noise and i think the above functions are related to **random** noise....that is why i asked for a code other than the functions...
Thank you...

I am trying to build a simple transmitter and receiver in simulink. Output of **random** **number** **generator** multiplied with PN **generator**. Then, after bpsk modulation and raised cosine pulse shaping it is fed to awgn channel. I need to know the parameters for this design and ways to reduce BER.

To clarify, the upper two bits as the feedback taps only works for a few lengths. Simply try a 3b lfsr, 4b lfsr, and 5b lfsr. The 3b/4b will work, but the 5b lfsr will have cycles of different length based on the initial value of the state register. If you want to use two taps, try the 15b lfsr as the two msb's are correct for a sequence of leng

I made a true **random** **number** **generator** from a 74HC595 shift register and a 74HC04 hex inverter. With the addition of a 4538 precision monostable and a few passive components, I had a **random**ly twirling laser cat

Possibly, but the **number** may be cyclic because the timer will update at a regular rate and will always have the same start value. In other words, you may get something which looks **random** but gives the same pattern sequence after each processor reset. If you are finding a truly **random** sequence I would suspect it is because 'i' and 'start' (...)

Hi
write an LFST code **generator**(u can find on the net) then treat its output as a floating point **number** between 0 and 1 then multiply it by a **number** that you want to have jitter for example you want to have 0 to 10 percent jitter so multply by 10 then you will have a **random** **number** between 0 and ten. then (...)
