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

We can pull all that together into an educational model for two SDRs talking to each other, but it’s going to require two parts: modulation and demodulation. Guess what?

There are many differences between information communication and audio algorithms. Information communication primarily ...

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, ...

In this paper, BPSK modulator and demodulator are purely design by using Hardware Description Language (VHDL) and implementing it on Spartan 3E FPGA kit.

A versatile four-quadrant analog multiplier core from Analog Devices, the AD633, is widely used in applications like modulation and demodulation, automatic gain control, power measurement, and ...

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 ...
