The invention relates to automation and may find a note as an external information channel of digital devices,

The aim of the invention is to expand the field of application of the device by providing decryption of a sequence of binary codes.

The drawing shows the functional diagram of the device for a particular implementation.

The device for decoding a binary code contains a block 1 of decoders of P elements OR 2, where P 1, P are self-removable memory blocks 3.

The self-locking memory block 3 is made on trigger 4 and delay element 5.

In the drawing, positions 6-8 denote the device input, the first and second device outputs, respectively.

The device works as follows.

When a sequence (alphanumeric word, message) of length P 1 of binary characters in parallel code arrives at the information inputs 6 of the device, pulse signals (logical O) appear on the corresponding outputs of block 1. If at the corresponding output of block 1, to which the first block 3 is connected, there appears a pulse signal from a specific sign, then on the output of block 3 there appears a signal of logical o, which arrives respectively at input, one of element 2. At The next pulse signal at the other corresponding output of block 1, to which element 2 is connected by the second input, establishes a logical signal at the output of the latter.

O, which is recorded in the second block 3, etc.

At a set time after recording, the blocks 3 alternate in turn, i.e. at the outputs of blocks 3 logical 1 are set.

Claims (2)
