Here, the envelope of the carrier can be seen to change in line with the modulating signal. This is known as Amplitude Modulation (AM). Figure 3-2. An amplitude modulated signal. The demodulation ...

Amplitude modulation (AM) is the most common type of digital modulation. ... First, the modulation and demodulation processes use two signals in quadrature with one another.

Demodulation of frequency modulation (FM) signals can be done in many ways. There are FM discriminators, ratio detectors, ... Figure 1 Slope detection method where a bandpass slope below the resonant ...

But for a weekend project, [Vinod.S] took the ultrasonic transmitter and receiver from a distance-meter module and used amplitude modulation to send music ultrasonically from his laptop to a ...

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.

Having studied the case of two-level amplitude modulation, we next investigate the accuracy of CNN-based demodulation for data encoded via four-level amplitude-modulation.

DiBcom and TeamCast have teamed up to provide programmable mobile TV solutions that can be configured similarly to meet the modulation and demodulation requirements of current broadcast standards, ...
