Question

1) Based on the sequential circuit and answer the following questions SOV a) Write equations for J, K, T, and Z in terms of the input X and the current state given by flip flop outputs QA, QB b) Based on these equations and the properties of JK and Toggle FF's fill out the state table CURRENT NEVT STATE OUTPUT QA QB X- O X=1 X-OX=1 QAQB QAQB 0 0 STATE NEXT STATE OUTPUT c) Based on the State table provide the state diagram d) Complete the timing tracing below for the state machine. Continue values as far as possible X 1 0 0 1 0 0 QA 0 QB 1

Answer 1

I have solved only the first problem. Please post one question at a time. The complete solution for the first problem is in the attachment.

(a) from the above sequential circuit, J = 2, k = 2 & 3), (t = xA; (Z = (a + 2B) x 1 Thus J, K, T and I are represented interns of input x and current state QA OB
