A new approach to realizing the analog signal source for digital phase modulation, or the approach to storing PSK signal waves, is described.
本文介绍了一种实现数字调相系统模拟信号源的新方法,即PS K信号波形存贮法。
By peak value sampling the information of baseband signal can be obtained from an am signal directly. By frequency conversion sampling the carrier wave's frequency of a PSK signal can be cut down.
