Description of laboratory model

A laboratory model is executes on the personal computer. A code (7, 4) is described by generator matrix

G = .

The control by model is produced by the left mouse button. The putting of errors produces by setting in «1» digit position (positions) of errors block e ₁, e ₂, e ₃, e ₄, e ₅, e ₆, e ₇ (which must contain an error). A model produces conversion of code word on the encoder output to code word on the decoder input by the rule = Å e_i, for i = 1, 2, …, 7.
