There is this question that i don't really get the solution:
Design a pulse-mode circuit having two input lines x1 and x2, and one output line z. The circuit should produce an output pulse coincide with the last input pulse in the sequence x1-x2-x2. No other input sequence should produce an output pulse. Use T-FF: T = 1, C acts as input
First, I don't really get the part in step 4 and 5 where do they get the table with Transition and C?
second,I don't really understand step 6 where you implement the equation, Why do we have to use negative edge triggered T flip-flop? why not positive edge triggered T flip-flop?
thank you in advance :)
