Analog switches are electronic components that control the flow of analog signals. They can connect or disconnect different parts of a circuit, allowing signals to pass through or be blocked. This functionality is essential in various applications, such as audio devices and communication systems, where managing signal paths is crucial. These switches operate by using control voltages to determine whether the signal should be allowed through. Unlike digital switches, which deal with binary signals (on or off), analog switches handle a continuous range of voltages. This makes them versatile for tasks like mixing audio signals or routing data in telecommunication systems.
