Audio Jammers

Hi..
I need some information on Audio Jammers. I have to implement Audio
Jammers in MATLAB and then have to convert the MATLAB into C-code and
to TI DSK CCS.

Jamming is performed by transmitting a signal to the receiving antenna at the same frequency band or sub-band as the communications transmitter transmits. I think you can acheive this by generating a sinosoidal wave in the frequency band of interest with a random phase. Try this in MATLAB and see whether it works as a jammer. I think it will, but I am not sure, since I have not modelled a jammer before. Writing a program for jammer would not be a difficult task in MATLAB. But you may have to put some effort to reproduce it in C, and more effort to do the same in an assembly language. MATLAB to C convertor is there, but it may cost you around $6000 extra for an inefficient conversion. - Krishna

Isn't that an RF jammer? A good audio jammer is a nearby air-raid siren or rock band. Jerry -- Engineering is the art of making what you want from things you can get. �����������������������������������������������������������������������

Ya, then we can use Korn's Twisted transistor to simulate audio jammer. How can simulate RF jammer by the way? Will a sine wave of random phase do? Or do I have to generate random noise and multiply (modulate) it with a sine wave and take it to the desired frequency? - Krishna
