moise generator with power amp in a freq range

[hasan_lebnani]

hello all
how to create random noise generator sing matlab

random noise generator not white noise
and then power amp to amplify the power of the noise


thanks in advanced

Thank you for posting this copy of your other thread in this RF section because I assumed it was for making audio noise.
Look in Google: white noise is random noise. Google shows hundreds of noise generator circuits.
I do not think your old SIM program knows anything about noise and the simple circuits that make it. Most simple circuits use current in a zener diode to make noise.

I guess I answered this request elsewhere. Without any specifications there is nothing to add. Generating wideband high-power noise is technically possible but no purpose was indicated. If used for jamming, legal action will be taken by government officials.

The is Impulse noise which has the same spectrum as White Noise but Pink Noise is acoustically preferred at -3dB per octave or 1/2 pole filtered and Brown Noise is -6dBoctave or 1pole filtered

PRSG digital noise depends on maximal sequence length and clock rate otherwise it is fairly short loop in seconds or less but otherwise, same spectrum as white noise, but diode thermal noise is best source.
