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 ...

The design process involved the following steps: Circuit Simulation: The circuit was simulated in LTspice software.; PCB Design: Schematic and layout routing were completed using PCB design ...

This project involves the simulation, design, and analysis of Amplitude Modulation (AM) and Demodulation. The main objectives are: AM Modulation: Generating an AM signal using a switching modulator ...

MIMO radar transmits quadrature signal. It forms a low gain and wide beam which has strong anti-interference ability in the space. The modulation and demodulation circuits of QPSK have been designed ...

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.
