Amplitude Modulation

Amplitude Modulation. Amplitude Modulation. Amplitude Modulation is a process where the amplitude of a carrier signal is altered according to information in a message signal. The frequency of the carrier signal is usually much greater than the highest frequency of the input message signal.

Preemphasis and Deemphasis Filtering

Preemphasis and Deemphasis Filtering. In Fig. 6.4, the noise PSD at the output of the demodulator in PM is flat within the message bandwidth. However, for FM, the noise power spectrum has a parabolic shape. This means that FM performs better in low-frequency components
