Double Sideband Modulation and Demodulation (DSBSC)

WebThe DSBSC AM Modulator Passband block modulates using double-sideband suppressed-carrier amplitude modulation. The output is a passband representation of the modulated signal. Both the input and output signals are real scalar signals. If the input is u ( t) as a function of time t, then the output is. where fc is the Carrier frequency parameter ... WebSSB modulation is produced by filtering out all of one sideband of a DSB signal, while VSB is produced by leaving a vestige of one sideband and all of the other sideband of a DSB signal. Such sideband rejection can be effected by a sideband filter at the output of the DSB modulator, which consists of a multiplier as pointed out previously. biozakjes actionWebThis difficulty suggests another scheme known as vestigial sideband modulation (VSB), which is a compromise between SSB and DSB-SC forms of modulation. In VSB modulation, one sideband is passed almost completely whereas just a trace or vestige, of the other sideband is retained. bioy xavier
