It concludes with an example from the university course that the Radio Design 101 series is derived from, showing how the entire FM broadcast band is downconverted and how an IF filter can be used to select the desired channel based on the frequency the LO is tuned to. https://youtu.be/nGOxNGZQ0EM |
