Tips ： The following is the main body of this article , The following cases can be used for reference

One 、 Determine the function according to the logic circuit diagram

use multisim The logic analyzer analyzes the logic circuit diagram accurately and quickly
The circuit diagram is as follows ：

The truth table and the simplest expression are obtained from the logic analyzer , As shown below ：

Two 、 Design the logic circuit according to the requirements of the topic

Can be used between MULTISIM Logic converter to complete the design ,
1、 Set in the logic converter according to the required functions A\B\C Three input signals , Then perfect the output signal as required ：
2、 Convert the output signal into the simplest logical expression , And realized by logic gate ; As shown in the figure below ：

The circuit diagram of the design is as follows ：

Similarly, the four person voting device is designed as follows ：
