I am working on radio project for school. We we given a whole circuit to test. My question is that I want to change the detector circuit (AM envelope detector) with a better one. Any suggestions will be much appreciated.
The local oscillator frequency and RF amplifier's tuned frequency are changed in a super-heterodyne radio, the IF frequency does not get changed.I'm trying to use the IF transformer for tuning. I want to use it in junction with a capacitor to tune for a range of frequencies between 1230kHz and 1530kHz.
