In the field of satellite communication,digital channelization techniques are used more and more widely.The analog-to-digital converter,one part of the digital channelizer,plays a great important role in the digital channelization techniques.Based on the elementary theory and performance of ADC,the effect on digital modulated signals exerted by the different number of quantization bit are discussed and simulated.
