ABB DSTC 452 modem

Modulation is to use baseband pulse to control a certain parameter of the carrier waveform

to form a signal suitable for line transmission. Demodulation is to remove the carrier from the

analog signal transformed by the modulator to restore the original baseband digital signal when

the modulated signal reaches the receiving end. The use of modems can also convert audio signals

into higher frequency signals and convert higher frequency signals into audio signals, so another purpose

of modulation is to facilitate line multiplexing in order to improve line utilization.
