Thread: operations in the frequency domain

Hi Pierre,

I think some operations can only be done in the time domain. But with
"writesp" one can write the spectra into files that can be read as if
they were regular time domain files.
Something like:

fft
writesp AM signal.e signal.n
r signal.e signal.n
*now operations..*
(there might be a better way to do this)

ciao
Andreas

Hello,
How is it possible to perform operations in the frequency domain with sac?
For instance, once the fft of two time series have been computed, how
can I divide one spectra by the other?
