LTspice

LTspice is a Windows utility that allows you to create and test electrical circuit layouts. The program functionality provides the ability to simulate the operation of various equipment to test the integrity, output signal and so on. The application is completely free and has a highly intuitive English-language interface.

Development of circuits

When a person starts the utility, the working area of the editor will appear in front of him. Here the user is allowed to design layouts on the principle of a constructor. All available elements are located in the built-in catalog, and they can be placed on the scheme at your discretion. Among the available objects are: voltmeters, transistors, connecting wires, diodes, ammeters, resistors, coils and so on. If necessary, a person is able to manually design a new element. Since in the process of working on the circuit, the user can begin to gradually get confused in the multitude of elements, the utility allows you to add notes to the segments of the circuit. This makes it easier to understand the layout, especially for those who have not developed the project.

Simulation

The key feature of the program is the simulation of the functioning of the created projects. With the help of this option, a person can test the equipment before its production. The algorithm built into the utility is able to calculate noise characteristics, if any, integrity, harmonic distortion and many other parameters. At the same time, the user can customize the operating mode of the device to test it under different loads.
