Tags Add Tags amplitude modulation analog communication carrier wave communications message signal modulation modulation index. Amplitude modulation AM generaton a modulation technique used in electronic communication. 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.

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 – Wikipedia

Views Read Edit View history. The DSBSC generation using balanced modulator based on nonlinear resistance characteristics of diode is given below in Fig1. Engineering in your pocket Download our mobile app and study on-the-go. The above equation shows that carrier has been cancelled outleaving only two sidebands and the modulating frequencies. It is used wves radio data systems.

The modulated output currents of the two diodes are combined in the center tapped primary of the output transformer, which then gets subtracted. This consists of a message signal multiplied by a carrier signal.

DSB-SC is generated by a mixer. This is best shown graphically. By using this site, you agree to the Terms of Use kf Privacy Policy. You are now following this Submission You will see updates in your activity feed You may receive emails, depending on your notification preferences.

Below is a message signal that one may wish to modulate onto a carrier, consisting of a couple of sinusoidal components with frequencies respectively Hz and Hz.

Updated 20 Jan This file generates the amplitude modulated signal and DSBSC wave for given carrier wave frequency, message signal frequency and modulation Index. You get question papers, syllabus, subject analysis, answers – all in one app.

The equation above shows that by multiplying the modulated signal by the carrier signal, the result is a scaled version of the original message signal plus a second term.

Conventional AM consists of the two sidebands and a carrier where the major transmitted power is concentrated in the carrier which contains no information.
