Signal Switches, Multiplexers, Decoders are all logic electronic devices that act on signal control and transmission. The signal switch usually consists of an input port, a control port and an output port, and the design principle is based on the switching characteristics of transistors or Fets. When the control signal meets certain conditions, the signal switch allows the signal to be transferred from the input port to the output port; Otherwise, the signal transmission is blocked. A multiplexer is an integrated circuit that can select and output one of multiple input signals onto a single output line. The multiplexer contains a selection control input and multiple data inputs, as well as an output. The design principle is based on a combination of logic gate circuits, which determines which data input is selected and transmitted to the output by selecting different states of the control input. A decoder is an electronic device that converts an encoded input signal into a set of output signals, each of which corresponds to a specific state of the input signal. The decoder usually consists of an input port, multiple output ports, and (optionally) an enable port. Design principle, the decoder contains a series of logic gate circuits, through the combination of logic to achieve the input to output mapping relationship.
Application
Signal Switches, Multiplexers, Decoders all play a key role in a variety of electronic devices. In the communication system, the signal switch is used to realize the switching and routing of the signal to ensure the correct transmission of the signal. In the field of automation control, signal switches are used to control the start, stop and state transition of equipment. Multiplexers are widely used in the field of communication and data transmission, such as Time division multiplexing (TDM) and frequency division multiplexing (FDM) systems. Multiplexers can combine multiple low-speed signals into one high-speed signal for transmission, improving channel utilization. In addition, the multiplexer is also widely used in computer bus, network interface card (NIC) and other occasions to achieve effective data transmission and distribution. Decoders play an important role in computer systems and embedded systems. In the computer, the decoder is used to convert the address signal sent by the CPU into the control signal of the corresponding storage unit or peripheral to realize the read and write operation of data. In embedded systems, decoders are used for address decoding, function selection, etc., to ensure that the system can correctly execute instructions and respond to external events. In addition, the decoder is also widely used in digital display, LED driver and other occasions to achieve signal to display conversion.
