Question 1

A sequential pattern detection circuit (state machine) has input A and output Y, which becomes 1 whenever input pattern of 1 1 0 is detected on the input

- Draw the state transition diagram for this circuit. Simply use state names S0, S1, S2… without any state encoding
- Using one-hot-encoding draw the state transition table. Clearly show input(s). present state and next state variables and output(s).
- Write next state and output equations.

Answer #1

design a moore sequential circuit with one input x and one
output z such that z=1 if the total number of 1's received is odd
and the total number of 0's received is an even number greater than
0. (6 states)
sample input x: 010011101010010101101
z: 001000001000001000001
derive the starte diagram. use one-hot state assignment for the
design. use DFF and draw the circuit

Create a FSM that detects the input bit pattern ‘01’. The output
will be ‘0’ until the exact pattern ‘01’ is received. At the point
of receiving ‘01’, the FSM will output 1, and then go back to
output ‘0’ until the next ‘01’ is received.
1) Draw the Moore FSM diagram for the above
2) Write the FSM tables:
a. State Assignment (Gray Encoding)
b. State Output
c. State Transition Tables
3) Simplify the Output logic (use K-Map if...

Design a sequential circuit which has an input line x
and an output line y.
The circuit receives input from a single source in the
form of a string of ‘1’ s and 0’s .
The output goes to ‘1’ once three consecutive ‘1’s are
seen on the input, and remains 1 as long as it continues to receive
‘1’ on the input line. If it receives a ‘0’ the output goes to ‘0’
again..

Mealy state machines.
(a) Design a Mealy state machine to detect the sequence 10010.
There is a single input “x” and a single output “z”. The output is
set to 1 when the sequence is detected. Design the state machine
using gates and flip-flops in the standard way, i.e., begin with a
state transition diagram and state transition table, do plain state
assignment (e.g., for three state variables, first state is 000,
next is 001, and so on), use K-maps...

Design an even parity detection circuit. A parity bit is an
error checking mechanism. Your circuit will count the number of 1’s
in a stream of bits. If the number of 1’s is even, the circuit
turns on an output called Y. Assume a single bit at each cycle –
call the input X. Do not use an accumulator or counter. Design the
even parity detection circuit using J-K flip-flops. Your answer
must include: a. The state diagram. b. The...

1) Design a sequential circuit with two D flip-flops,
A and B, and one input, x. When x = 0, the
circuit state does not change. When x = 1, the circuit stops
through the state transitions
from 00 to 01, from 01 to 10, from 10 to 11, finally back to 00 and
the sequence repeats.

b. Find the table of states
c. Find the equations of state
d. Find the logic diagram

Create a sequential circuit Moore machine with 2 D flip flops
and 3 states (s0, s1, s2), with any gates needed.
The machine must be able to recognize any amount of xy=10
