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 ...

Accurate demodulation of two-level amplitude-modulated data requires only the ability to identify the positions of bright points in modulation blocks.

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

Amplitude or frequency modulation and demodulation can be performed with the modulation option (HF2LI-MOD) in HF2LI. Using this modulation option, the oscillators that drive the demodulator of Figure ...

This is a combination both phase and amplitude modulation where multiple bits are represented by unique carrier phase-amplitude combinations. Each combination is called a baud or symbol.

AM, or amplitude modulation, was the earliest way of sending voice over radio waves. That makes sense because it is easy to modulate a signal and easy to demodulate it, as well.

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 ...

This article investigates the demodulation capabilities of a DSSSsuper-regenerative receiver. Starting from the general expressionthat characterizes the receiver's behavior, we demonstrate that afew ...
