Generation of dsbsc waves
A DSB-SC signal can be obtained by simply multiplying modulating signal x(t) with carrier signal cosωct . So we need to use a device called product modulator for the generation of … See more The balanced modulators are used to suppress the unwanted carrier in AM wave . Fig.4 : Block Diagram of Balanced Modulator The carrier and modulating signals are applied to … See more A linear modulator is a system whose gain or transfer function can be varied with time by applying a time varying signal at certain points . The gain is proportional to signal f(t) . G = K f(t) Where … See more The block diagram of a balanced modulator is shown in fig.5 .

WebDefinition: DSB-SC is an amplitude modulated wave transmission scheme in which only sidebands are transmitted and the carrier is not transmitted … WebIn this process, the message signal can be extracted from DSBSC wave by multiplying it with a carrier, having the same frequency and the phase of the carrier used in …
WebThe first technique uses the balanced modulator, filter, oscillator, etc., to generate SSBSC. The other method is the phase shift method. Here, we will discuss both methods in detail. The block diagram of the SSBSC modulator is shown below: It consists of two balance modulators, two bandpass filters, and two oscillators. http://ecelabs.njit.edu/ece489/dsbsc_generation.php
