Q.What is demodulation?

[!TLDR] Demodulation is the reverse of modulation -- recovering the original signal back out of the modulated carrier wave. [!ANSWER] The process of recovering …

Section 13.5.2 defines demodulation as the process of regaining the original signal from a modulated wave, describing it explicitly as the reverse process of modulation. While modulation happens at the transmitter (impressing the low-frequency signal onto the high-frequency carrier), demodulation happens at the receiver, stripping the carrier back away to recover the original signal that a user can actually make use of (for example, …
