Spectral Properties and Band-Limiting Effects of Time-Compressed TV Signals in a Time-Compression Multiplexing System

Time-compression multiplexing (TCM) is a technique whereby multiple signals can be multiplexed together in a common communication channel for transmission. 1,2 A simple illustration of this method is shown in Fig. 1 where x{t) is a continuous waveform intended for transmission. It is first divided into segments of T seconds each; and each segment is time compressed by a factor a (a > 1), resulting in a 2167 Fig. 1--A simple illustration for TCM.
