Case1: when Q=0. For s = 0. ( here j = 0, k = 0. Latch mode, same state) For s = 1. ( j = 1, k = 1, Toggle Mode, change the state). Case2. when Q = 1. For s = 0. ( here j = 0, k = 0. Latch mode, same state) For s = 1. ( j = 1, k = 1, Toggle Mode, change the state). 0 votes 0 votes jatin khachane 1 commented Jan 11, 2019 reply Follow Share When Q = 1 and s = 0 ==> I0 = 1 and I1 = 0 , s = 0 ==> Y = I0 ==> Y = J = K = 1 toggle Qn = 0 hence state change on Q =1 on s = 0 0 votes 0 votes balchandar reddy san commented Jan 15, 2019 reply Follow Share @kumar.dilip Case2. when Q = 1.
