The application is a computer learning tool designed to explore conditional graphical notation typical block diagrams, the principles of operation of digital devices such as combination, as well as studies of their work in static mode. The application can be useful to teachers of technical schools, students of the digital circuitry, as well as for those who want to self learn the basics of digital electronics.

The application covers a wide range of combination devices, ranging from simple gates to complex functional units. A total of 15 units sold, which include:
- Disjunctors
- Conjunctor
- Inverter
- Item Schaeffer
- Item Pierce
- An EXCLUSIVE-OR
- An element of a complex basis (AND-OR-NOT)
- Buffer element with three-state output
- Encoder
- Decoder
- Multiplexer
- Demultiplexer
- Digital comparator
- A half-adder
- A one-bit adder

The basis of the application of the program model - the emulator. Emulation allows to demonstrate the functioning of the algorithm selected device using an interactive interface elements, which include indicators of input and output signals signalov.Lyuboe change together at the entrance of the combination devices leads to a change in its output signal. In turn, any changes to the input signal enough to touch the screen.

Touching any input device entails changing the values ​​of the input signal to the other: a unit is replaced by a logic zero and vice versa. Displaying the values ​​of logical variables input and output device is a color indicator: blue LED corresponds to a logical 0, red - logic 1, and gray - a high impedance state output.

When using the emulator it is possible to increase or decrease the size of the image, as well as get acquainted with the typical block diagram or a brief theoretical information about the selected device.
