This repository contains the code and documentation for a Pulse Code Modulation (PCM) project ... to-digital converters (ADCs), digital-to-analog converters (DACs), sampling circuits, and ...

Pulse modulation may be subdivided in to two types analog and digital. In analog the indication of sample amplitude is the nearest variable. In digital the information is a code ... Connect the ...

Abstract: Pulse-position modulators are used for remote sensing ... insensitive to clock frequency and other sources of timing errors by use of a demodulator feedback circuit. The modulators are ...

Low temperature Nb/AlOx/Nb digital Single Flux Quantum (SFQ) circuits have been designed and fabricated ... produced and operated at up to 5.4 GHz. On chip modulation and de-modulation of these PRES ...

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.
