In: Electrical Engineering
a) Design and implement a combinational circuit that converts excess-3 to BCD code using 2-input NAND gates. (Design: means show all the steps)
b) Draw the logic diagram of 2x4 decoder using NOR gates only. Include an enable input. (describe in details)
c) Construct a 5-to-32-line decoder with four 3-to-8 decoders with enable and a 2-to-4-line decoder. Use block diagrams for the components. (Describe in details while you are constructing the required circuit)
d) Design a 2-bit multiplier using a set of Multiplexers and 2-input NAND gates (Design: means show all the steps)
