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.

Frequency modulation (FM) is used worldwide for high-fidelity broadcast radio communication. This paper presents a MATLAB implementation of a stereophonic FM transmitter and receiver. Simulations are ...

Amplitude modulation is defined as the multiplication of one time-domain signal by another time-domain signal, or mixing of the message signal with the amplitude of the carrier signal. The signals may ...

This repository contains a MATLAB simulation of Fast Orthogonal Frequency Division Multiplexing with Index Modulation (Fast-OFDM-IM), a next-generation waveform combining Fast-OFDM and subcarrier ...

Certain fundamental characteristics of the theory of frequency modulation for arbitrarily large degrees of modulation and unrestricted modulation frequencies are developed from the differential ...
