The mathematical representation of this process is shown below, where the product-to-sum trigonometric identity is used.

It is used for radio data systems. This resultant signal is then passed through a low pass filter to produce a scaled version of original message signal.

Double-sideband suppressed-carrier transmission DSB-SC is transmission in which frequencies produced by amplitude modulation AM are symmetrically spaced above and below the carrier frequency and the carrier level is reduced to the lowest practical level, ideally being completely suppressed.

Double-sideband suppressed-carrier transmission

This page was last edited on 30 Decemberat In the picture shown below we see four peaks, the two peaks below Hz are the lower sideband LSB and the two peaks above Hz are the upper sideband USBgemeration there is no peak at the Hz mark, which is the frequency of the suppressed carrier. The modulated output currents of the two diodes are combined in the center tapped primary of the output transformer, which then gets subtracted.

This file generates the amplitude modulated signal and DSBSC wave for given carrier wave frequency, message signal frequency and modulation Index. DSB-SC is generated by a mixer.

The DSBSC generation using balanced modulator based on nonlinear resistance characteristics of diode is given below in Fig1. The diode dsbsx the balanced modulator use the nonlinear resistance property for producing modulated signals.

Double-sideband suppressed-carrier transmission – Wikipedia

From Wikipedia, the free encyclopedia. Explain its generation using balanced modulator. Double Sideband Suppressed Carrier DSBSC is an amplitude modulation technique in which the modulated wave contains both the sidebands along with the suppressed carrier.

DSB-SC transmission is a special case of double-sideband reduced carrier transmission. Conventional AM consists of the two sidebands and a carrier where the major transmitted power is concentrated in the carrier which contains no dsbzc.

This is apparent when the spectrum of the output signal is viewed. Views Read Edit View history. Updated 20 Jan Download our mobile app wsves study on-the-go.

This is best shown graphically. Full depth modulation requires carrier re-insertion. The modulating frequencies from the output is eliminated by the tuning of the output transformer, which results in the below equation of the generated DSBSC wave.

Amplitude modulation AM is a modulation technique used in electronic communication. The output of the balanced modulator contains two sidebands and sum of the harmonic components. By using this site, you agree to the Terms of Use and Wavex Policy.
