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 modulation, unlike in AM, the wave carrier is not transmitted; thus, much of the p… Web1. Learn your material on DSB/SC modulation. 2.

WebDec 31, 2024 · The frequency spectrum of the DSB-SC signal: The standard DSB-SC equation is given as: S D S B ( t) = A c m ( t) cos 2 π f c t Assuming a single tone message signal as: m ( t) = A m cos 2 π f m t The DSB-SC signal can be written as: S D S B ( t) = A c A m 2 cos 2 π ( f c + f m) t + A c A m 2 cos 2 π ( f c − f m) t WebA straight forward approach to demodulate a DSB-SC signal for comparison is to simply multiply the signal with the recovered carrier. Carrier recovery can be done by simply squaring the signal, which will create a dominant tone at twice the carrier frequency which can then be divided by two.

This is true as long as the message signal has no DC component. What happens is that the spectrum of the message signal is simply shifted to ± ω c, so DC gets mapped to the carrier frequency ω c, and as ...
