I have generated a random gaussian distribution number and multiply these stationary-type waveform with a sutible deterministic time function(z(t)) . now i multyply the FFT waveform by a filter function (kanai-tajimi and penzien) B(iw)=z(iw)*H1(iw)*H2(iw) i use fft to get the Z(iw) but how i should obtain the filter function w1 and tesi is constant number H1(iw)=[1+2*i*tesi*(w/w1)]/[(1-w^2/w1^2)+2*i*tesi*(w/w1)]
what vector should i use instead of w?
