发明名称 Digital superheterodyne receiver and baseband filter method used therein
摘要 A digital receiver includes an antenna for picking up signals, a converter for converting an incoming signal to a predetermined intermediate frequency, and baseband processor. The receiver further includes an analog/digital converter using oversampling relative to the bandwidth of the signal and receiving the intermediate frequency signal at its input, and decimation filters receiving the output signal from the analog/digital converter and having their outputs connected to the baseband processor.
