Analog data can also be represented by digital signals by use of a _______.Select one:ModemTransmitterReceiverCodec

The correct answer to the question is Codec.

Explanation:

A Codec (short for coder-decoder) is a device or software that compresses and decompresses digital signals, enabling the conversion of analog data into digital form and vice versa. In telecommunications, codecs facilitate the transmission of audio and video data over digital networks. When analog signals, such as sound from a microphone, are captured, the codec encodes this sound into a digital format that can be transmitted over various communication channels. Upon reaching the destination, the digital data is then decoded back into an analog signal by the codec, allowing it to be played back through speakers or other output devices. This process is crucial in applications like VoIP calls, streaming services, and video conferencing, where high-quality audio and video are required over digital networks.

Other options presented, such as Modem, Transmitter, and Receiver, serve different roles in communication systems. A modem converts digital data to analog for transmission over traditional phone lines and vice versa. A transmitter sends out signals, while a receiver captures incoming signals. However, none of them specifically perform the function of encoding and decoding that is characteristic of a codec.
