Demodulate → It is formed from "de-" (meaning down or away) and "modulatus" (from Latin, meaning to measure or adjust). The word "demodulate" means to remove modulation from a signal, effectively adjusting it back to its original form.
Think of 'removing' ('de-') the 'adjustment' ('modulatus') from a signal to understand that demodulate means to revert a signal to its original state.
