A) voice simultaneously in two ways.
B) on the same frequency as they receive.
C) using digital encryption technology.
D) voice and data simultaneously.

Question

Quizplus · Accepted Answer

Multiplex systems are designed to transmit multiple signals simultaneously, including both voice and data. They achieve this by dividing the available bandwidth into multiple channels or streams, each of which can carry a separate signal. This enables higher efficiency and capacity in communication systems. Options A and B are incorrect because multiplexing generally involves transmitting multiple signals over one channel or frequency, rather than two-way transmission or using the same frequency for transmit and receive. Option C may be used in some multiplexing systems, but it is not a defining characteristic of multiplexing itself.
