Question

6. Develop the state diagram for a Moore state machine that detects a sequence of two or more consecutive 0's in a serial string of bits coming through an input line "X". (When two consecutive zeros are detected, the output is set to 1 and stays there is the zeros keep arriving. If a one occurs in between the zeros, the machine will go back the initial state) Additionally, make sure that the design is self-correcting. Complete the design using T flip-flops and draw the final circuit.

Answer 1

"(Moure Design) we have to design system to detect two (or) more Consecutive zeros through input x A implies Initial state Let: B implies State with one zero (0) C implies State with two Consecutive Zero (""00"") x implies input line y implies output line as A is initial State (y = 0) as B has only one zero, it's State output is zero (y = 0) And, C has 2 Consecutive zeros, here it output is one(y = 1) the State diagram can be drawn as when Stak A: Initial State Stak B: State with '0' Stak C: State with '00' \r\n Stak Assignment pq A implies 00 B implies 01 C implies 10 as 3 States are tran 2 Flip, Flops required Stak tabh can be drawn as: when circuit encounter these states then it should be routed to initial stake for the SELF-CORRECTING design "
