1- explain the similarities and differences between double sideband suppressed carrier (DSB-SC)

1- explain the similarities and differences between double sideband suppressed carrier (DSB-SC) and double sideband transmitted carrier (DSC- TC) amplitude modulations in terms of: (a) the modulation process (b) the waveform after modulation (c) the frequency components after modulation (d) the occupied bandwidth of the modulated signal (e) the demodulation process 2- explain why AM (DSB-TC) is limited to 33% power efficiency and the consequence of trying to exceed that value. 3- compare DSB-SC, DSB-TC in terms of: (a) bandwidth requirements (b) power efficiency 5- explain the process of coherent detection (synchronous detection) of amplitude modulated signals and its limitations
