Explanation:
Detailed explanation-1: -Digital modulation is the process of encoding a digital information signal into the amplitude, phase, or frequency of the transmitted signal. The encoding process affects the bandwidth of the transmitted signal and its robustness to channel impairments.
Detailed explanation-2: -Amplitude modulation is employed in India for radio transmission .
Detailed explanation-3: -Encoding is about converting digital or analog data to digital signal, whereas modulation is about converting digital or analog data to an analog signal. Encoding is used to ensure efficient transmission and storage, whereas modulation is used to send the signals to a long way.
