How fast of a sweep are you talking about? Seconds or milliseconds? Is
this the 50 and 80 ms bit that the paper mentions?
If we use a rising
frequency sweep, the harmonics will be gener-
ated ahead of the same frequencies appearing
in the signal. So after deconvolution, any dis-
tortion will appear as spurious peaks in negative
time in the impulse response, and most of it can
then be edited out easily.
What a great way to use an artifact of the FFT to one's advantage. Awesome!
