Question

Design a MEALY algorithmic state machine which functions as a binary sequence detector. There is an input YIN which receives the binary sequence and an output HBELL which activates the bell. Draw two ASM charts (flow chart and bubble) but do not design the circuit. The detector rings a bell when it receives two binary ones in a row. Then it keeps ringing the bell as long as it keeps receiving ones, otherwise it must start over.

Answer 1

else Mealy state machine * It has snput YIN and output HBELL. The output HBELL which activates Bell when state machine defects two binary one's in a row. After detecting once, it keeps ringing bell as long as it keeps receiveing ones, it must start over means goes to Starting state. * so, we need to deségn Mealy State Machine for detected overlapping sequence of 11". * to defect buo bit sequence using mealy type Fsm, we need 2 states. Let states be so, si and initial State after seset és "so" when once sequence detected it goes to starting state so" when ou detected after sequence.
