Basic Flip-Flop Circuit Quiz

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.
