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.

Moreover, modulation–demodulation and filtering technology are used to improve the accuracy and reduce the noise of the detection circuit. This paper is conducted in the context of MEMS gyroscope. The ...
