Embodiment 1

[0018] Embodiment 1: as Figure 1-5 As shown, a conversion method among D, JK, and T flip-flops, including a method for converting JK flip-flop 2 into D flip-flop 1, and a method for converting K flip-flop 2 into T flip-flop 3;

[0019] The method for converting the JK flip-flop 2 to the D flip-flop 1 is as follows: because the JK flip-flop 2 has two input terminals JK, and the D flip-flop 1 has only one input terminal D, the logic function formula of the JK flip-flop 2 is: , the logic function of D flip-flop 1 is: ,Right now , set the J terminal of JK flip-flop 2 as the D input terminal, set ,but , so , that is, the J-terminal signal of JK flip-flop 2 can be converted to D flip-flop 1 by inverting the J-terminal signal to the K-terminal, that is, the J-terminal of JK flip-flop 2 is connected to the two input terminals A1 and B1 of the NAND gate V1 at the same time, and the NAND The output terminal Y1 of the gate V1 is connected to the K terminal of the JK flip-flop...

Abstract

The invention relates to a conversion method among D, JK and T triggers, and belongs to the technical field of the digital electronics. The invention comprises a method for converting a K trigger intoa D trigger, and a method for converting the K trigger into a T trigger. The JK trigger, the D trigger and the T trigger can flexibly perform the conversion use through the conversion method disclosed by the invention, a chip resource can be sufficiently utilized, and other chips can be immediately applied to replacing and processing when some chip is in shortage, thereby improving the resource use ratio, and the circuit can be flexibly designed.

Description

technical field [0001] The invention relates to a conversion method among D, JK and T flip-flops, belonging to the technical field of digital electronics. Background technique [0002] In digital electronic technology, flip-flops have a memory function and are widely used in circuit design and production. It is often necessary to use them in conjunction with logic circuits and convert their functions according to design requirements. The commonly used types of flip-flops include JK flip-flops, There are three types of D flip-flops and T flip-flops. Each flip-flop chip contains multiple sets of sub-flip-flops. When designing multiple flip-flop combinations, selecting each flip-flop chip you need will cause waste of resources; The conversion method between flip-flops can make full use of chip resources, thereby improving the utilization rate of resources, and can flexibly design circuits. Contents of the invention [0003] The invention provides a conversion method among D,...
