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.

To use SDR for modulation and demodulation, you need a hardware platform, such as a computer or a smartphone, that can connect to a radio frequency (RF) front-end, such as an antenna or a transceiver.

Download this article in PDF format. Modulation and demodulation provide the means to transfer information over great distances. As noted in the first part of this article (see “Basics of Modulation ...

SDR, or Software-Defined Radio, is a radio system that uses software to handle tasks like modulation, demodulation, filtering, and encoding. This means it can use common hardware like a computer ...

Most amateur radio operators already own a computer and a radio and the Bi-LIF connects the two together at the IF level. This allows a software application that uses a DSP (Digital Signal Processing) ...

Objective: To simulate QPSK signals, focusing on modulation, transmission, and demodulation processes. Current Status: This project is under active development. The notebook includes initial work with ...

A Convolutional Neural Network (CNN) is a highly utilized deep learning model in various domains, including computer vision and natural language processing. Disruption of the network structure of CNN ...

The past 20 years have witnessed unprecedented progress in brain–computer interfaces (BCIs). However, low communication rates remain key obstacles to BCI-based ... developed a new joint ...

This project involves the simulation, design, and analysis of Amplitude Modulation (AM) and Demodulation. The main objectives are: AM Modulation: Generating an AM signal using a switching modulator ...

Phase-modulation and -demodulation techniques are more complex than modulation and demodulation based on amplitude and frequency. However, they provide the benefit of higher data rates for the amount ...
