Modulation is a device in music that allows a transition from one key to another. There are many types of modulation: Common chord modulation pivots on a chord common to both keys. Parallel modulation moves between major and minor keys of the same tonic.
In telecommunications, modulation is the process of conveying a message signal, for example a digital bit stream or an analog audio signal, inside another signal that can be physically transmitted. Modulation of a sine waveform transforms a baseband message signal into a passband signal. A modulator is a device that performs modulation. A demodulator (sometimes detector or demod) is a device that performs demodulation, the inverse of modulation. A modem (from modulatorâdemodulator) can perform both operations.
