(a) Test Signal; (b) Distorted Test Signal, after being convolved with simulated signal
processing channel's impulse response; (c) Deconvolved Test Signal, produced using frequency domain
filtering following by the IDFT; (d) Deconvolved Test Signal, produced by using the IDFT on the
reciprocal of the DFT of the channel impulse response to produce a time domain filter which is circularly
convolved with the distorted test signal.
