Digital signal vs.Analog signal /96 ■Noise Noise can not be accumulated and propagated in digital signal process. DSP is insensitive to environment. ■ In analog signal process,noise is treated same as the signals. Environment affect the analog signal process significantly. ■ Store and recovery of signals Flexible and easy for digital signal storage. It is hard for analog signal storage,especially in high accuracy requirement. Always be true? 2021年2月 22021年2月 2 Digital signal vs. Analog signal  Noise  Noise can not be accumulated and propagated in digital signal process.  DSP is insensitive to environment.  In analog signal process, noise is treated same as the signals.  Environment affect the analog signal process significantly.  Store and recovery of signals  Flexible and easy for digital signal storage.  It is hard for analog signal storage, especially in high accuracy requirement.
