My tutorial has this question but there are 2 things I dont understand when I was givven the answer. 1) To calculate fmax, why is hold time not included? 2) Since there are 2 flip flops, why isnt Tmin doubled? 3) Why is the ouput of the second flip flop the inverse of the first? I thought they should be the same? Eg, when Q1 = 1 J2 =1, this set the flip flop and Q2 should be one. Where have I gone wrong? I know how to draw Q1 but I am unsure of Q2.
