Flip-Flop Design Using LabVIEW VIs: SR, JK, T, and D

labview flip flop vi digital logic circuit design

This article covers the design of various flip-flops using LabVIEW Virtual Instruments (VIs). The flip-flops discussed are SR, JK, T, and D flip-flops.

T Flip-Flop LabVIEW VI Block Diagram

The T flip-flop takes two inputs: the T input and the Clock input. It produces two outputs: Q(t) and the inverted Q(t), often denoted as Q’(t) or ¬Q(t).

Truth Table of T Flip-Flop:

T InputQ(t+1)
0Q(t)
1Q(t)’

Figure 1 shows the block diagram of the T flip-flop LabVIEW VI.

SR Flip-Flop LabVIEW VI Block Diagram

The SR flip-flop takes three inputs: S, R, and Clock. It generates two outputs: Q(t) and Q(t)’.

Truth Table of SR Flip-Flop:

JK Flip-Flop LabVIEW VI Block Diagram

The JK flip-flop uses J, K, and Clock as inputs and produces Q(t) and Q(t)’ as outputs.

Truth Table of JK Flip-Flop:
