Question

A sequential circuit takes an input stream of 0's and 1's and produces an output stream of 0's and 1's. Initially it replicates the input on its output until two consecutive 0's are encountered on the input. From then onward, it produces an output stream, which is the bit-wise complement of input stream until it encounters two consecutive 1's, whereupon the process repeats. An example input and output stream is shown below.

The input stream:	101100|01001011	0|11
The desired output	101100|10110100	0|11

J-K master-slave flip-flops are to be used to design the circuit.

Give the minimized sum-of-product expression for J and K inputs of one of its state flip-flops

Answer 1

first i read the question wrongly instead of J-K master-slave flip-flops i read as J-K Flipflop... after i solve the question i realize the point but for my satisfaction i uploaded this solution
