demodulate
This term is a technical operation used primarily in telecommunications and signal processing. It describes the precise reversal of modulation, where a high-frequency carrier wave is stripped away to reveal the original baseband signal, such as audio or data. It carries a connotation of recovery and extraction, functioning as the necessary counterpart to the encoding process.
In practical application, the word is almost exclusively used in engineering and scientific contexts. It is rarely used metaphorically, as its meaning is tied strictly to the physical manipulation of electromagnetic waves or digital streams within a receiver circuit.
