ELEG 2903 / CENG 2113: HW#4 (due Thursday, October 23) Question 1 is worth 4 points and the rest are worth 2 points each, for a total of 14 points. Show your work, and check your answers. 1) Design a minimal implementation of the following 4-bit comparator: 4-bit comparator A(3:0) F(1:0) B(3:0) If A = B -> F = 00 If A < B -> F = 01 If A > B -> F = 10 F = 11 is undefined 2) Write the expression for the following circuit in minimal SOP format. 3) Implement the following function using an 8-to-1 MUX, where

Unformatted text preview: w , x , and y are connected to the select lines, S 2 , S 1 , S , respectively: f(w, x, y, z) = m(1, 2, 4, 5, 8, 10, 11, 15). 4) Construct a 16:1 MUX using only 2:1 MUXes. 5) Is a 2:1 MUX a complete logic set? Explain. 6) Implement the following function using NAND NAND logic: f = AB + AC + BC + CD + AD, assuming maximum 4-input gates. The resulting circuit should have 3 gate delays....
