Two voltage (channel 1 and 2) and two current (channel 1 and 2) sensors indicate measured voltage with 16-bit binary values on their output lines, S15 to S0 .
1. Instantaneous power is a product of voltage and current. Write the behavioral VHDL code to analyze the power in each channel (1 and 2) and display in 4-bit binary values issuing a 1-bit address P .
