SU549887A1 - Signal duration to digital converter - Google Patents

Description

one

The invention relates to analog-to-code converters, can be used in devices of computer technology, automation and remote control.

Known Converter signal duration into a digital code containing a clock generator, triggers and counters. This transducer works on the principle of counting pulses produced by a clock generator from the moment a signal arrives until its termination, it is unreliable.

A converter is also known that contains a clock pulse generator, a pulse counter connected to a generator by means of a control logic circuit.

This converter is also unreliable and uneconomical.

The purpose of the invention is the evolving of reliability and efficiency, which is achieved by the fact that the signal duration converter is a digital code containing two keys and a serially connected threshold device and a clock generator, equipped with a resistor on cylindrical magnetic domains with a generator and the domain annihilator and four drivers. the first of which is connected to the output of the clock generator, the output through the second driver to the input of the register, the second output through the key and the third driver to the second input of the second istra, and the third output of the first shaper kgaoch through the second and fourth driver coupled to the third input register.

The drawing shows an electrical functional diagram of the device.

The converter contains a threshold device 1, a clock generator 2, a shaper of current information offset 3, a shaper of information shift current 4, a generator of control current of the generator and annihilator of domains 5,6, a register on magnetic cylindrical domains 7 with a generator and annihilator of magnetic domains 8 and 9, keys 10 and 11.

The converter works as follows.

At the moment when the signal arrives at the converter input, the threshold device 1 generates a signal at the input of the clock generator 2, working on the driver of the information current shear programs 3, which are synchronized separately by the drivers 4,5 and 6. Under the influence of the current of the driver 5, the necessary number of cylindrical magnetic domains, and under the influence of the current shaper 4, the encoded information is entered into register 7 for free bit positions. The coding continues until the threshold device 1 generates a signal for the end of the measurement interval and thus stops the generator 2.

If it is necessary to destroy the previously encoded information, close the key 11, and the driver 6 excites the annihilator and synchronously with the generation of new cylindrical magnetic domains, the previously recorded code is destroyed.

To force the register to clear, the clock signal is sent to the input of the clock generator. They close the key. Neither opens the key 1 and turns on the domain generator 8. Then the process proceeds as described above.
