● Telecommunications: For data modulation, signal amplification, and timing control.
Detailed Explanation
In telecommunications, mixed signal circuits are crucial for various processes such as data modulation, signal amplification, and timing control. Modulation involves taking an information signal (analog) and varying a carrier signal (also analog) to transmit over distances.
