Question #2. Design of a Sequential Circuit: A SEQUENCE DETECTOR that detects the sequence 10 must be designed whose present output z(k) is set to one when the past input u(k-1) is one and the present input u(k) is zero, where for the other three possible combinations of the input pair u(k-1), u(k) the present output z(k) is set to zero.

Sequence detector: The machine has to generate z = 1 when it detects the sequence 1011
Sequence detector: The machine has to generate z = 1 when it detects the sequence 1011. Once the sequence is detected, the circuit looks for a new sequence. The signal E is an input enable: It validates the input x, i.e., if E = 1, x is valid, otherwise x is not valid. Draw the State Diagram (any representation), State Table, and the Excitation Table of this circuit with inputs E and x and output z. Is this a Mealy or a...
Design a MOORE FINITE STATE MACHINE for a Sequence Detector that detects sequentially the number 1510 in a stream of input bits
Design a MOORE FINITE STATE MACHINE for a Sequence Detector that detects sequentially the number 1510 in a stream of input bits. Label the input w. The output z is equal to 1 if the number 1510 was detected. After detecting the pattern (1510), the machine goes back in the initial state S0. a) Draw the state diagram for the FSM. Add an asynchronous Reset, active LOW. b) How many FFs do you need to implement this FSM? Note: Label the states S0,...
