Deconvolution of Log Sine Sweep
The “time reversal mirror” technique is employed: the
system’s impulse response is obtained by convolving the measured signal y(t) with the time-reversal of
the test signal x(-t). As the log sine sweep does not have a “white”
spectrum, proper equalization is required
