noise generator on pspic

[hasan_lebnani]

hello everyone

please can anyone help me
i need a circuit for a noise generator for pspise that it can give me a randomly noise in a range of frequency

and how to attach a power amplifier for it

thanks in advanced

Why don't you look in Google at the hundreds of noise generator circuits it shows? Almost all of them use a zener diode with some current in it and an amplifier.
Don't you know how much power and what impedance speaker you need?
Why don't you know how to connect the generator to the input of the amplifier?

I doubt that your p-spice SIM program knows anything about the noise the circuit will make.

actually am not using it for speakers
i just want to test a random noise variable with time and covers a range of frequencies

You never said what the noise is for and never said the range of frequencies.
True noise produces random frequencies. It is wideband unless you filter it.

Since you never said what is the noise transducer, frequencies and power required then we do not know which amplifier circuit you need.

Are you the guy who is making an illegal radio jammer?

 

[hasan_lebnani]

why you call it illegal?
its a project for a uni
tell me why its illegal

Generating ANY interference that may jam existing legal communication is illegal in civilized countries.
Attaching a power amplifier to a noise source indicates the device is a jammer, therefore illegal.
Try it and you will see what happens.

I think I answered your request elsewhere, with some technical discussion.
Indicate the purpose of the device and specifications, otherwise this talk is a waste of time.
