I have a feeling it's very well-known...one case is to have fH=2*fL,
which is the Morley wavelet...

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 this one be called?
cosinc is already taken--it's the name of the derivative of the
sinc. sincos? sounds silly
