We call this design the Super-Heterodyne Receiver! A super-heterodyne receiver can be viewed as simply as a fixed frequency homodyne receiver, proceeded by a frequency translation(i.e., down-conversion) stage. 1 IF Gf f= ˆit() 1 0 IF IF ff ff = ≈ ≠ ≈ T T acos tω s Acos tω LO f IF s LO=ff−

oh well tanx for posting, but ive read the wiki site b4, at least some of it. i do understand what "heterodyne" means. my aim is to design a local oscillator for fm reciever using a FET , using any convenient oscillator type. any circuit diagram with explanations would do.tnx b1u3sf4n09 Joined May 23, 2014 113 Oct 8, 2014 #4 J.o.s.h said:
