INTRODUCTIONA digital multiplexer or data selector is a logic circuit that accepts several digital datainputs and selects one of them at any given time to pass on to the output. Primarily theyare used for data routing which selects a transmission path for outgoing data according tothe coding criteria established by binary inputs. The routing of the desired data input tothe output is controlled by SELECT inputs (often referred to as ADDRESS inputs).Figure 4.1 shows the functional diagram of a general digital multiplexer. The inputs andoutput are drawn as wide arrows rather than lines; this indicates that they may actually bemore than one signal line.IorI₁Data InputsIN-1DataInputSELECT inputsFigure 4.1: Functional diagram of digital multiplexer (MUX)A demultiplexer performs the reverse operations. It takes a single input and distributes itover several outputs based on the selector. Figure 4.2 shows the functional diagram fordigital demultiplexer (DEMUX). The large arrows for inputs and outputs can representone or more lines. The select inputs code determines to which output the DATA input2Data Outputwill be transmitted. In other words, the demultiplexer takes one input data sources andselectively distributes it to 1 of N output channels just like a multiposition switch.SELECT inputsDIGITAL ELECTRONICS STB24403Data OutputsON-1Figure 4.2: Functional diagram of digital demultiplexer (DEMUX)For this lab session, you are required to first build your own multiplexing system whichwill include the combination of a 4:1 multiplexer (MUX) and a 1:5 demultiplexer(DEMUX).

According to the question, we need to design a multiplexing system by using 4:1 Mux, and 1:5 Demux.
