Frequency Demodulation Frequency Modulation Detector

FM Modulation and Demodulation Goal: The goal of this experiment is to become familiar with FM modulation and demodulation. Theory and background: 1. FM modulation: Frequency modulation (FM) is a process in which the carrier frequency is varied by the amplitude of the modulating signal (i.e., intelligence signal). The FM signal can be expressed by the following equation: ( ) = cos( ) = cos (2

FM Demodulation Detection Frequency Modulation

Frequency Modulation (FM) is a form of modulation in which changes in the carrier wave frequency correspond directly to changes in the baseband signal. FM is considered an analog form of modulation because the baseband signal is typically an analog waveform without discrete, digital values.

Even though there are different methods for modulation and demodulation processes, each has its own advantages and disadvantages. For example, AM is used in shortwave and radio wave broadcasting; FM is mostly used in high-frequency radio broadcasting, and pulse modulation is known for digital signal modulation.

Frequency Demodulation Frequency Modulation Detector

Frequency Modulation (FM) It is a process in which the frequency of the carrier is varied in accordance with the instantaneous value of modulating voltage . The amount of change in frequency is determined by the amplitude of the modulating signal.

FM Demodulation Detection Frequency Modulation

THEORY: Modulation is defined as the process by which some characteristics of a carrier signal is varied in accordance with a modulating signal. The base band signal is referred to as the modulating signal and the output of the modulation process is called as the modulation signal. Amplitude modulation is defined as the process in which is the amplitude of the carrier wave is varied about a

ES442 Lab 6 Frequency Modulation and Demodulation

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 of bandwidth consumed. Phase modulation is the basis for many digital modulation formats, in which a modulated signal is divided into in-phase (0 deg.) and quadrature (90 …
