I want to learn more about digital modulators (ASK, FSK, PSK) Modulators and Oscillators, like I want to know how to design (circuit component by component) a modulator and an Oscillator.
I also want to know how to design to the point of knowing how to design it by circuit componnets, like what r we trying to do to the signal that comes into the modulator and what r we trying to do when the signal comes into the oscillator and y do we need an oscillator for......
Is there a website that show like a full complete tutorial explaning what is each circuit component for and shows the change in the waveform at each node or after each cicuit component so I can follow and see what is hapening to the signal.
Thank you very much
