Study Notes
Flip-Flop Circuit Basics
- The basic function of a flip-flop circuit is to store a bit of information.
Flip-Flop States
- A flip-flop has two states: set (1) and reset (0).
Flip-Flop Construction
- A basic flip-flop can be constructed using NOR gates or NAND gates.
Flip-Flop Outputs
- The two outputs of a flip-flop are Q (next state) and Q' (previous state).
Flip-Flop Initialization
- Flip-flops are initially set or reset using asynchronous inputs, such as PRESET (PR) and CLEAR (CLR).
Flip-Flop Initialization States
- PR=0 and CLR=1 indicates that the flip-flop is set to 1 (set state).
SR Flip-Flop Characteristics
- The characteristics equation for a SR flip-flop is Q(next) = S + R'Q.
J-K Flip-Flop States
- A J-K flip-flop is in its reset state when J=0 and K=1.
J-K Flip-Flop Race Condition
- A race condition occurs in a J-K flip-flop when J=K=1.
D Flip-Flop Characteristics
- The characteristics equation for a D flip-flop is Q(next) = D.
T Flip-Flop Characteristics
- The characteristics equation for a T flip-flop is Q(next) = TQ' + T'Q.
SR to JK Flip-Flop Conversion
- The excitation functions to convert an SR flip-flop to a JK flip-flop are J = S + RQ and K = R + SQ'.
SR to D Flip-Flop Conversion
- The excitation functions to convert an SR flip-flop to a D flip-flop are D = S + RQ.
Flip-Flop Reset and Set Conditions
- Both PR and CLR are activated when PR=CLR=0.
J-K Flip-Flop Toggle Condition
- When both J and K inputs are set to 1, the J-K flip-flop toggles (changes state).
J-K Flip-Flop Set Condition
- The set state is activated in a J-K flip-flop when J=1 and K=0.
