Modulation-demodulation (M-D) amplifiers are four-terminal unidirectional amplifiers in which amplitude modulators with conversion gain are followed by demodulators. This paper describes wideband ...

This repository contains simulation files and circuit diagrams for Phase Shift Keying (PSK) modulation and demodulation. The project includes: LTspice Files: Detailed circuit simulations for PSK ...

He’s broken down the modulation and demodulation circuits into their basic op-amp stages with examples of what the signal should look like on a scope after each stage. That’s the beauty here.
