Restore PCM Telemetry Signal Waveform by Making Use of Multi-sample Rate Interpolation Technology

摘要

There are two misty understandings about PCM telemetry system in conventional concept: Waveform can not be restored accurately; to be resotred accurately, a measured signal must be sampled at a higher sample rate. This paepr discusses that by making use of multi-sample rate DSP technology, the sample rate of a measured signal can be reduced in transmission equipment, or system precision can be reatined even if the performance of low pass filter declined.
