I have a feeling it's very well-known...one case is to have fH=2*fL, which is the Morley wavelet... On 2/3/07, Charles Henry [EMAIL PROTECTED] wrote: There's a function I think could be useful for system response measurement: f(x)=sin(pi*(fH-fL)*t)*cos(pi*(fH+fL)*t)/t it's basically the ideal

There's a function I think could be useful for system response measurement: f(x)=sin(pi*(fH-fL)*t)*cos(pi*(fH+fL)*t)/t it's basically the ideal bandpass function, it's fourier transform is 0.5 between fL and fH and 0 everywhere else. There's another related signal, the sinc... but what should
