What is analog modulation and its types?

Modulation techniques are roughly divided into four types: Analog modulation, Digital modulation, Pulse modulation , and Spread spectrum method . Analog modulation is typically used for AM, FM radio, and short-wave broadcasting.

And analog modulation is the procedure of transmitting low-frequency signals such as TV signals or audio signals with that of high-frequency carrier signals like that of radio frequency signals . In this type of modulation, a bandpass channel is required where it corresponds to the specified range of frequencies.29 Nis 2020
