为了从接收到的PCM码中还原出原始信号，阐述了一种由硬件实现帧同步，由串并转换器完成PCM码解调器的高速PCM码解调器电路。
This paper presents a high speed PCM demodulation circuit through which the serial parallel converter plays a role of demodulating and the hardware realizes frame synchronization.
接着，给接收到的异步蜂窝式通信信号的帧边界加时间标记。
Then a frame boundary of a received asynchronous cellular communication signal is time-tagged.
因此，在某些传输模式中，可能需要超过130毫秒来接收一个完整帧，故会延迟所接收的视频信号的解码与解调。
Thus, in some transmission modes, it may take more than 130 milliseconds to receive a complete frame, thereby delaying decoding and demodulation of the received video signal.
处理管线传输错误的一种方法，在这种方法中，接收方发现错误后简单地废弃后续帧，不发送确认信号。
A method for dealing with pipelining errors in which the receiver simply discards all subsequent frames, sending no acknowledgments.
图3示意性地示出了隔行到逐行扫描变换器，其接收基于场的输入信号并且生成基于逐行扫描帧的输出信号。
FIG. 3 schematically illustrates an interlaced to progressive scan converter which receives a field-based input signal and generates a progressive scan frame-based output signal.
