1. Answer the following: a. Design a three-input gate circuit with any combination of gates to get a HIGH output only when all inputs are HIGH. Draw the circuit. b. Design a three-input majority circuit whose output is "1" whenever two or more inputs are "1" and whose output is "0" otherwise. Use NAND gates to implement the circuit and display the output with an LED

(a) Consider the flipflop circuits below: (i) Name the 2 circuits given in the figure. Explain how they are different from each other. a. b.
