In electronics and telecommunications, modulation is the process of varying one or more properties of a periodic waveform, called the carrier signal, with a modulating signal which typically contains information to be transmitted.odulation in a modem is process of modification one of the parameters of carrier signal(periodical signal; sin/cos wave in this case) with the message signal(random digital signal in this case, string of 0âs and 1âs) so that can be transmitted over the network.
A modem performs this function. A modem converts digital information to analog information to transmit a signal over phone lines. The process of converting this signal in this manner is modulation. They also convert analog information back to digital information to receive data. This is called demodulation.
