Focuses on pulse code modulation (PCM), data transmission, and digital modulation techniques like ASK, FSK, and PSK.
In AM, the amplitude of a high-frequency carrier wave is varied in direct proportion to the instantaneous amplitude of the modulating signal.
Varying the strength of the carrier. Includes DSB-SC, SSB, and VSB techniques. Impulse response, frequency response, and transfer functions
