4-to-1 Multiplexer

Problem Description

Implement a 4-to-1 multiplexer that selects one of four input bits based on a 2-bit select signal.

Module Interface

• Inputs:
  • sel: 2-bit select signal
  • data: 4-bit input data
• Output:
  • out: 1-bit selected output

Expected Behavior

• sel = 00: output data[0]
• sel = 01: output data[1]
• sel = 10: output data[2]
• sel = 11: output data[3]
