Teletype receiver tester

The present invention relates to a teletype receiver tester.

So far in telegraphy, a teletype receiver tester is known from the Polish People's Republic patent description No. 94 472, the essence of which consists in a direct connection of the start generator with the tester's input, a potentiometer for regulating the width of the start pulse, a clock pulse generator, a circuit forming the end-of-cycle pulse and a telegraph speed switch, which has direct connection with an adjustable pulse frequency divider, where the clock pulse generator is indirectly connected to the end-of-cycle pulse forming system through an adjustable pulse frequency divider and a pulse frequency divider and a frequency divider with a constant division, which has a direct connection to the telegraph signs commutator, while the output register has direct connection to the telegraph characters memory, telegraph characters commutator, teletype power supply which is connected to the output to the teletype receiver. Also known from the practice of telegraphy is the station of measurement texts that use the source text from a perforated paper tape, read through an electromechanical automatic transmitter, which, by the essence of its work, introduces uncontrolled telegraph distortions and causes rapid wear of the read perforated tape. Laboratory electronic telegraphic measuring transmitters of source texts are also used, with a given, selected rate and type of telegraph distortions changed as needed, which meet only the hopes placed in them locally.

The essence of the teletype tester system achieved through a commutation unit cooperating with an arrhythmic signal transmitter consisting of a set of blocks for entering, programming and determining the amount of text distortion formed in the text production and separation blocks is that the arrhythmic signal transmitter has a distorted text control block connected to the input, programming and determining the value of the distortion of the texts and the distorted text regeneration block, which is connected to the output stage of the arrhythmic signal transmitter and the text generation and separation blocks, the output of which is connected to the distorted text control block, which contains a temporization pulse generator, identifying the commissioning of the system to work and end of the text segment whose output

154 188 controls the counter of text segments, which through multiplexers and demultiplexers programmatically setting the parameters of the text segment is connected to blocks for input, programming and determining the value of the text distortion, where in the block regenerating the distorted text, the text is regenerated by a D-type transducer, which is controlled by the circuit logic gates, the input of which are pulses with a block for generating and separating texts, and is fed through a typical protection set to the additional output of the transmitter of arrhythmic signals.

The advantageous effect of the application of the invention is reliable operation of the device and easy positioning of the text with a given degree of distortion.

The subject of the invention is shown in the drawing showing the device in a block diagram.

The teletype receiver tester consists of a transmitter which has a garbled text control block 1 which is connected to input 2, programming and warp value determination blocks 3 and a distorted text regeneration block 10. The distorted text regeneration block 10 is connected to the transmitter output stage 4 arithmic signals and text production and separation blocks 5. The output of block 5 is connected to the warped text control block 1, which contains a temperature pulse generator 6 identifying that the system is on and the end of a text segment, the output of which controls the text segment counter 7, which through the multiplexers 8 and demultiplexers 9 setting the program parameters of the text segment is connected to blocks for input 2, programming and determining the value of the distortion of the texts 3. In the garment regeneration block 10 the garbled text is regenerated by a D-flip-flop controlled by a gate system logic elements, to which the impulses from the text generation and separation blocks are fed 5 and is fed through a typical safety set to the additional output of the transmitter of arrhythmic signals 4.
