Pour le transporter, on utilise une « onde porteuse » de haute fréquence. L’ amplitude de l’onde porteuse est modulée par le signal électrique de basse fréquence. Ceci est effectué par un modulateur.

Modulation And Demodulation 415 Amplitude change of carrier = 0 Amplitude of normal carrier = A ∴ Modulation factor, m = 0/A = 0 or 0% (ii) When signal amplitude is equal to the carrier amplitude as shown in Fig. 16.3 (ii), theamplitude of carrier varies between 2A and zero. Experiment 2: Amplitude Modulation and Demodulation Objective Amplitude modulation (AM) is one of the simplest methods for modulating a sinusoidal carrier wave. Theﬁrst useof AM fortransmissionofvoice signalsbyradiocan be traced tothebeginning of the 20th century. Yet, AM continues to be used today in many communication applications

EXPERIMENT NO-1 AMPLITUDE MODULATION &DEMODULATION AIM: To study the function of Amplitude Modulation & Demodulation also to calculated the modulation index. APPARATUS : 1. Amplitude Modulation & Demodulation trainer kit. Amplitude modulation can be produced by a circuit where the output is product of two input DEMODULATION OF AM SIGNALS Demodulation: Restoring (or recovering) the message signal from the received † Amplitude of carrier is not important since it inﬂuences only the (W << fc) and if modulation factor is small enough („ < 1).

Amplitude Modulation. Among the types of modulation techniques, the main classification is Continuous-wave Modulation and Pulse Modulation. The continuous wave modulation techniques are further divided into Amplitude Modulation and Angle Modulation. A continuous-wave goes on continuously without any intervals and it is the baseband message signal, which contains the information. 5/9/2015 · These videos explain you what is modulation, different kinds of modulations like Amplitude Modulation(AM) and Frequency Modulation(FM),QPSK,QAM,Phase Modulat...
