Re: gamnitude range of a cepstrum



Try squaring the value of each bin. After all, a large negative peak can
also be your desired signal, right? (If not, this information is also
of
value.)

You might also just take the magnitude instead of the square, and see
which works better for you..

Normally you would consider the probability distribution of the noise
magnitude, and then you would set the threshold so as to fix a false-alarm
probability (hence the name CFAR - constant false alarm probability).. If
you do it this way, it should not matter whether you are using magnitude or
squared-magnitude.
