We want to design a digital circuit that converts Gray code (ABC) to Binary code (xyz). Set up a 8-to- 1 line multiplexer so that the output gives y as a function of ABC. "A" is given to the most significant bit of the control inputs of the multiplexer. "C" is given to the least significant bit of the control inputs of the multiplexer.

consider figure 1 answer the following

1. Consider the CRC generator shown below. Determine the output of the CRC circuit (i.e. Q4 Q3 Q2 Q1 Q0, expressed as a decimal number) for the input sequence "1010" (input one bit at a time, left to right). Assume the CRC circuit is initialized to state 11111. D Q0 Q2 Q4 Q1 Q3 Clock - Data In
