Compared to the simple diode needed to demodulate AM radio signals, the detector circuits used for FM are slightly more complicated. Wrapping your head around phase detectors, ratio detectors, ...

Abstract: In this article I present the components of a circuit that is designed to improve the signal/noise communications using frequency modulation. Circuit was made interposing between two active ...

This repository contains simulations of various digital modulation techniques using Python and NumPy/SciPy. The purpose is to visualize and understand baseband signal characteristics such as waveform ...

/ c ± n.m / for n = 0, 1, 2, 3, .... where n is the sideband pair number In this expression, the + indicates the upper sidebands, and the - indicates lower ones ...

Spread spectrum frequency modulation reduces EMI emissions, while an internal PMOS switch driver delivers robust short-circuit protection in boost and buck-boost topologies. The LT3795 incorporates a ...

The FM modulator circuit (frequency modulation) is built with a Motorola MC1648P oscillator. Two varactors, Motorola MV-209 are used to frequency modulate the oscillator. The 5000 Ω potentiometer is ...

The diagram utilizes two BC548 transistors, more importantly descent results although not as good as RF transistors which provide high performance at wide bandwidth. It also utilizes electret ...

Metric-Frequency Duality In this chapter, we will discuss the attempt to connect General Relativity with Quantum Field Theory by establishing a relationship between metric variations in GR and quantum ...
