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 ...

A research team led by Prof. Tian-Bao Ma from the Department of Mechanical Engineering at Tsinghua University has proposed a ...

LFOs, or low-frequency oscillators, can ‘modulate’ other parameters on a synth and it’s this ‘modulation’ that really takes ...

This report summarises that results of tests at three sites, using typical indoor aerials, to compare FM and AM systems for broadcasting. The main conclusions are as follows:- (1) The proposed BBC ...

Part 1 explains the basics of amplitude modulation (AM) and frequency modulation (FM), as well as their relative strengths and weaknesses. Part 3 discusses Direct Sequence Spread Spectrum (DSSS) and ...

Pulse amplitude modulation (PAM) is already a widely adopted technology in high-speed digital communications. But to understand why it has become ubiquitous in serial data standards, you first must ...

The final step is the amplitude modulation itself. Here, the changing amplitude of the original audio wave is used to modulate that of the high-frequency carrier wave.
