Download 2 1 Mux Logic Diagram PNG. Let us understand its function in a simpler way. The general block level diagram of a multiplexer is shown below. Design A Circuit Using Only 2 To 1 Multiplexers That Implements The Function Of An 8 To 1 Multiplexer Electrical Engineering Stack Exchange from i.stack.imgur.com First configuration uses three 2 to 1 muxes in a specific configuration as shown in the figure given below. We have taken a 2:1 mux as shown in figure 1 above, where based on control inputs, logic equation for the 2:1 mux is derived i.e. The circuit is designed with one input.

### So why isn't that answer sufficient?

We have taken a 2:1 mux as shown in figure 1 above, where based on control inputs, logic equation for the 2:1 mux is derived i.e. A multiplexer or mux is a combinational circuits that selects several analog or digital input signals and forwards the selected input into a single fig.5: — it outputs at any time are determined from the present inputs. The block diagram of 4x1 multiplexer is shown in the following figure.
