Question
Describe what a T-Flip Flop does in one sentence. What inputs does it have and how does it operate? Describe what a D-Flip Flop does in one sentence. What inputs does it have and how does it operate? Describe what a SR Latch does in one sentence. What inputs does it have and how does it operate? Which of the above three memory units uses the fewest gates? Below is a finite machine, circle and label the following portions of the state machine. Current state, Next state, Next state Logic, Output Logic, inputs, outputs, and input clock. What is the Boolean expression for Q_0*? What is the Boolean expression for Q_1*?Explanation / Answer
1). T (Toggle)- Flip-flop toggle its output or remain same as previous output depending upon the value of T at every edge of clock pulse.
Its input are- T and clock
output-- Q , Qb (bar of Q)
If T=1 , then at every clock edge Output Qi (present state)= BAR of Q(i-1) [previous state]
If T=0 , then at every clock edge Output Qi (present state)= Q(i-1) [previous state]
2).D Flip-flop passes its value on D to output at every edge of clock pulse.
Its input are- T and clock
output-- Q , Qb(BAR of Q)
If D=1 , then at every clock edge Output Qi (present state)= 1
If D=0 , then at every clock edge Output Qi (present state)= 0
