✦ Synopsis


A puke compressor is utilized in many aspects of signal processing. Compression is usually accomplished by using special matched-filter-signal pairs. An alternative method takes advantage of the fact that any linear dynamic system can be excited to produce a time-limited output. Accordingly for a given dynamic system a synthesis procedure is provided for stepwise-constant input pulses evoking a time-limited response.

Pairing the signal and system carefully leads to pulse compression. The Doppler invariant pulse compression is an important special case. Many examples are given.
