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.

There are many different varieties of modulation but they all fall into three basic categories, namely amplitude modulation, frequency modulation and phase modulation, although frequency and phase ...

Discussing the slope detection FM demodulation method where a bandpass slope is used to create a slope-induced amplitude modulation.

There are several modern digital modulation techniques that provide increased information capacity, higher data security and quicker system availability with great communication qualities.

This tutorial explains the fundamentals of time-, frequency-, and modulation-domain analysis from the perspective of several examples.

The resulting time-varying frequency, and thus varying phase of the vision carrier, is known as incidental phase modulation, ICPM. There are two basic types of circuits for demodulating ...

The modem in your home does both modulation and demodulation of data signals to enable internet — hence the name (Mo-modulator, Dem- demodulator).

"We plan to develop receiver circuits for the 300-GHz band as well as modulation and demodulation circuits that are suitable for ultrahigh-speed communications," said Prof. Fujishima.

Frequency Modulation (FM) sounds simple at first, but understanding the electronics behind modulation and demodulation of an FM signal can be confusing.
