Logic - Signal Switches, Multiplexers, and Decoders are integrated circuits used to route, combine, or decode digital signals in electronic systems. Signal switches enable the selection of multiple input signals for routing to a single output, while multiplexers facilitate the routing of a single input signal to one of several output channels. Decoders interpret encoded input signals and activate corresponding output lines based on predefined conditions. These logic devices play essential roles in data routing, selection, and processing in applications such as data acquisition, communications, and control systems.
