摘要
直流稳压电源由于电压波动而存在纹波,短波PSM发射机由PSM调制器控制产生阶梯状直流加音频信号,而该信号中存在阶梯纹波会影响发射机的失真指标,本文主要介绍PSM调制器纹波产生及消除纹波降低发射机失真的办法。
DC regulated power supply due to voltage fluctuations exist ripple. PSM short wave transmitters by PSM modulator control ladder DC and audio signal, and the signal exist ladder ripple effect of the transmitter distortion index. This paper mainly introduces the PSM modulator ripple generation and elimination of ripple method to reduce the distortion of the transmitter.
