WebIn SSB, whenever a sideband is moved throughout the filters, then the filter like bandpass cannot work completely in practice so some of the data may get lost. However, in DSBSC, two sidebands are transmitted to carry the waste data. Therefore to overcome this failure, a method is chosen called VSB modulation and it includes between DSBSC and SSB.

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. In the DSB-SC … See more DSB-SC is basically an amplitude modulation wave without the carrier, therefore reducing power waste, giving it a 50% efficiency. This is an increase compared to normal AM transmission (DSB) that has a … See more DSB-SC is generated by a mixer. This consists of a message signal multiplied by a carrier signal. The mathematical representation of this process is shown below, where the product-to-sum trigonometric identity is used.

WebFollowing is the block diagram of coherent detector. In this process, the message signal can be extracted from SSBSC wave by multiplying it with a carrier, having the same frequency and the phase of the carrier used in SSBSC modulation. The resulting signal is then passed through a Low Pass Filter. WebDSBSC envelope Now let us test the ideal envelope detector on a more complex envelope - that of a DSBSC signal. T7 remove the carrier from the AM signal, by turning ‘g’ fully anti-clockwise, thus generating DSBSC. Alternatively, and to save the DC level just used, pull out the patch cord from the ‘g’ input of the ADDER (or
