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 ...

1. Three basic digital modulation formats are still very popular with low-data-rate short-range wireless applications: amplitude shift keying (a), on-off keying (b), and frequency shift keying (c).

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.
