Abstract: A demodulator for receiving signals modulated in emergent time, comprised of an exponential time warping input stage, an FFT to convert to the frequency domain, and an exponential time warping output stage to map the recovered modulation onto the causal time domain. Overlapped blocks are correlated by summing the warped outputs, providing selectivity and gain. Tuning is by means of matching the warp rate of emergent time. A modulator performs the reverse function.
