The process of converting a modulated signal back into its original form, allowing the original information to be retrieved.
Demodulation is essential for receiving radio signals clearly.
Demodulation is formed from "de-" (meaning down or away) and "modulatio" (from Latin, meaning a measure or modulation). The word refers to the process of removing modulation from a signal, effectively bringing it down to its original form or measure.
Think of 'removing modulation' ('de-') from a signal to return it to its original 'measure' ('modulatio'). This helps you remember that demodulation means to take away the modulation.
