RF Modulation and Demodulation of Audio and Video Signals Any information that is broadcast over the airwaves is broadcast via what are known as radio waves. Radio frequency (RF) is the rate of oscillation or frequency at which a particular …
Frequency Modulation (FM) Audio Demodulator
https://www.vocal.com/video/fm-audio-demodulator/
A basic FM audio demodulator is shown in Fig.1. The RF FM audio signal is first down-converted to the baseband. The baseband FM signal is filtered in the main filter to attenuate adjacent channels and other out of band signals. Then, the CORDIC technique is …

This is what the old-school modems did in order to transfer binary data over the phone line (producing the typical modemish sound). It is called modulation. Then I need a reverse process - from the raw waveform samples, I want to obtain the exact binary data. This is called demodulation. Any bitrate will work for a start.

Frequency demodulation is an essential process in telecommunication engineering. It involves converting a signal from one frequency to another frequency. 1. Frequency Modulation: The frequency modulation technique is used in computing, radio broadcasting, single processing, telecommunications.

AMPLITUDE MODULATION AND DEMODULATION ©2017 Frank Dörenberg N4SPP V1.1 www.hellschreiber.com . Modulation is a technique to transmit information via radio carrier waveform. It is a non-linear process that generates additional frequencies, as we will see. Amplitude Modulation (AM) works by varying

Channels, modulation, and demodulation 6.1 Introduction Digital modulation (or channel encoding) is the process of converting an input sequence of bits into a waveform suitable for transmission over a communication channel. Demodulation (channel decoding) is the corresponding process at the receiver of converting the received waveform into a

Compared the original audio with demodulated audio. Finally, examined the myFFT of the demodulated signals and noted the differences. Results. The results were as expected. Was able to successfully modulate and demodulate two audio signals. The demodulated signal had some noise in it but was able to hear the audio.
Modulation and Demodulation

Modulation and Demodulation • Principle borrow from radio telecommunication –Take a wide band signal [few Hz to kHz] –Modulate it with a single frequency “the carrier signal” which is the frequency associated to a given station –Emit the signal –Given the station frequency, a receiver follows a demodulation
