Two voltage and two current sensors indicate measured voltage with 16-bit binary values on their output lines, S15 to S0.
1. Show with a block diagram how to use multiplexer modules to allow a 16-bit microprocessor to read any one of these sensors using its input lines, D15 to D0, by issuing a 2-bit address, A1A0.
2. Write the structural (gate-level) VHDL code to implement this device.
