For the logic diagram below, complete the timing diagram. You can assume the gate delays are much shorter than the clock period. Is this a Mealy machine or a Moore machine and why? ECE 152A – Summer 2009 8/10/2009 Homework #5 Solution – Page 2 of 20 ECE 152A – Summer 2009 8/10/2009 Homework #5 Solution – Page 3 of 20 Problem #2. For the network shown below: 1. Construct a timing diagram for the input sequence: X = 0 1 0 1 0 1 1 1 0 Assume that: 1) X, A and B are all initially equal to 0 2) All transitions of the input X occur on the rising edge of the clock 3) gate delays are much shorter than the clock period. Include all inputs (CLK, X) state variables (A, B) and outputs (Z) in your timing diagram. ECE 152A – Summer 2009 8/10/2009 Homework #5 Solution – Page 4 of 20 2. Construct next state maps for the network. 2....
