Double sideband suppressed carrier modulation At the beginning of the explanation of amplitude modulation, we explained the AM radio system, but the term for amplitude in the theoretical expression was complex. If the amplitude of the carrier wave is simply changed and mathematised, it is as follows. This modulation method is called DSB-SC (double sideband suppressed carrier modulation). In double sideband suppressed carrier modulation, the carrier signal is removed or suppressed by the balanced modulator, and the modulated signal containing no carrier as shown in Fig. 5-2c.
