The above circuit uses two JK Flip-Flops, each based on a D Flip-Flop as follows: (Scheme 2:) Assuming that the Q value of both JK flip-flops are ' O ' before the clock pulses for the first time (in Scheme 1), and that both flip-flops only update on the rising edge, what are the values of Q1 and Q2 when the clock has pulsed 4 times? Assume that we're checking the values of Q1 and Q2 after enough time has passed after the pulse that if they were going to update, they've updated. Q1: 1, Q2: 1 Q1: 1, Q2: 0 Q1: 0, Q2: 1 Q1: 0, Q2: 0
