Adaptive FM/AM radio architecture

A radio frequency (RF) receiver includes a local oscillator (LO) module that receives a control signal and that generates a LO signal at a LO frequency that is based on the control signal, a LO mixer module that generates an intermediate frequency (IF) signal based on a radio frequency (RF) signal a...

Zusammenfassung:A radio frequency (RF) receiver includes a local oscillator (LO) module that receives a control signal and that generates a LO signal at a LO frequency that is based on the control signal, a LO mixer module that generates an intermediate frequency (IF) signal based on a radio frequency (RF) signal and the LO signals, a complex intermediate frequency (IF) mixer module that generates a baseband signal based on the IF signal and an IF oscillator signal, and a channel monitoring module that generates the control signal based on the baseband signal.
