Hey all,
I've spent much of my time learning and building signal processing circuits for musicians (eg. distortion, wah, phasers, etc.) And started to learn about AM and FM radio. I've found AM to be real easy to understand and to implement. But with FM, it's more of a challenge to understand it. For instance, when looking at the following link, I see a tank circuit triggered via a transistor. Couldn't one replace the tank circuit with a sine wave oscillator and turn that on and off via a transistor or even a switch? Would that still be frequency modulation?
Thanks.
