pulse modulation 脉冲调制法;[脉波调变] In communications, a signal transmission system in which the information content is impressed upon a pulse train by adjusting the pulse amplitude (PAM), pulse duration (PDM), pulse position (PPM), or by binary codes based upon the presence and absence of pulses (PCM). 在通信技术中,一种信号传输方法,其中,靠调节脉冲幅度(PAM)、脉冲宽度(PDM)、 脉冲位置(PPM)或根据脉冲有无的二进制代码(PCM)把信号内容加到一个脉冲串上。 参阅pulse amplitude modulation, pulse duration modulation, pulse position modulation, pulse code modulation。 |
