Question

Quizplus · Accepted Answer

PCM (Pulse Code Modulation) is a technique used in V.90 modem to digitize analog signals. It is a method where the amplitude of the analog signal is sampled at regular intervals and converted into a digital format. The resulting digital signal is then transmitted over the telephone line. CODEC (Coder-Decoder) is a device or program that converts an analog signal into a digital signal and vice versa. MP3 and WAV are file formats used for digital audio storage and playback, and are not directly related to modem technology.
