1. What is a signal switch?
A signal switch is an electronic component that controls the path of a signal. It can be mechanical (such as a toggle switch, button, etc.) or electronic (such as a transistor, field effect tube, etc.). The main function of a signal switch is to switch the signal path between different circuits, or to turn on/off a specific signal line.

2. What are multiplexers in digital systems?
Multiplexers in digital systems use digital control signals to determine which input should be selected and passed to the output. This selection is usually based on the state of a set of binary select lines.

3. What is the use of a decoder?
The role of a decoder is to restore the encoded data to the original information or trigger the corresponding function based on the input code. For example, a BCD to 7-segment decoder is a common decoder used to convert binary coded decimal numbers into signals that drive a seven-segment display.
