Wouldn't this mean that you're at least one waveform in the past? If you time compress the
greater than midpoint signal, and expand the below the midpoint signal,  than all I have
to do is feed a constantly rising signal - soon the signal I am outputting from the time
compressor hasn't happened yet.
