Implement the circuits as described below. A priority encoder has four inputs, D0, D1, D2 and D3. D0 has the highest priority and D3 the lowest. The encoder has two outputs X and Y. Implement the priority encoder. Design a one-input, one-output Finite State Machine (FSM) that operates as a serial 2’s complementer. The FSM accepts a string of bits from the input and generates the 2’s complement of each bit at the output. The circuit can be reset asynchronously...

A comparator circuit has two 1-bit inputs A and B and three 1-bit outputs G (greater), E (equal), and L (less than). That is, G is 1 if A > B (0 otherwise), E is 1 if A == B (0 otherwise), and L is 1 if A < B (0 otherwise). a. Draw the truth table for a 1-bit comparator (the table has 2 inputs and 3 outputs). b. Implement G, E, and L circuits using only...
Design a circuit with three inputs (A, B, C) and two outputs (F1, F2). The first output F1 is logic 1 if the number of l’s in the binary number is less than the number of O's, otherwise F1 is logic 0.

Design a combinational circuit which inputs a three-bit binary number, and outputs the input number PLUS two if the input is less then or equal to 3, and outputs the minus two if the input is greater than 3. This should include the truth table for the operation, the karnaugh map(s), and the resulting circuit.
