Digital Systems

Definition

Digital systems are electronic systems that process and manipulate information in the form of discrete values, typically represented by binary code (0s and 1s). They are integral to modern audio technology, especially in wireless microphone systems, where they enable clearer sound transmission, enhanced signal processing, and reliable communication over various distances.

5 Must Know Facts For Your Next Test

1. Digital systems in wireless microphones convert sound waves into digital signals, which reduces noise and improves audio quality.
2. These systems often use compression algorithms to minimize data size while maintaining sound fidelity for transmission.
