"WebDec 27, 2024 · So this type of AM (DSB-SC) really results in a suppressed carrier, i.e., the modulated signal has no component at the carrier frequency. 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 ... " - A dsb-sc modulation generates a signal

Balanced modulator consists of two identical AM modulators. These two modulators are arranged in a balanced configuration in order to suppress the carrier 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. In the DSB-SC modulation, unlike in AM, the wave carrier is not transmitted; thus, much of the p… 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.
