Demodulation: meaning, definitions and examples

signal processing

Demodulation is the process of extracting the original information-bearing signal from a modulated carrier wave. In telecommunications, it is a crucial step in the reception of radio signals, where the modulated signal is transmitted over the air and needs to be converted back to its original form for interpretation. This process is essential for enabling devices like radios and televisions to process and reproduce audio and visual information. Various techniques are employed depending on the type of modulation used, such as amplitude modulation (AM) or frequency modulation (FM).

Examples of usage

• The demodulation of the received signal allowed for clearer audio playback.

• In digital communication, demodulation is vital for decoding the transmitted data.

• Engineers focused on improving the efficiency of the demodulation process.

• Without proper demodulation, the quality of the received signal would degrade significantly.
