Questions

To implement a parallel-to-serial data converter using a multiplexer in Logisim Evolution, you can follow these steps:

1. Open Logisim Evolution.
2. Create a new circuit.
3. Add an 8-bit input bus for the data.
4. Add a multiplexer component. You can find it in the "Wiring" folder.
5. Connect the 8-bit input bus to the input lines of the multiplexer.
6. Add three select lines for the multiplexer. Since there are 8 possible combinations (000 to 111), you need 3 select lines.
7. Connect the select lines to the select inputs of the multiplexer.
8. Add a clock source to control the stepping of the select lines sequentially.
9. Add an output pin for the serial output.
10. Connect the output of the multiplexer to the output pin.

Here's a simple schematic representation:

Clock Source (Controls select lines)

You can then configure the clock source to step through the select lines sequentially from 000 to 111, causing the 8 bits of data on the input lines to be output serially on the Serial Output pin.
