SU364107A1 - FREQUENCY DIVIDER - Google Patents

Description

one

The invention relates to immersion technology and can be used, in particular, in telemetry devices that convert frequency of sensors.

Frequency dividers are known for matching a pulse sensor with a recording, for example, telemetry, system that contains a trigger counter K with an immersion driver at its input and a mixer, one input of which is connected to the output of the counter, and the output of the keys to the output divider.

However, these dividers have an error that is commensurate with their division ratio.

In order to eliminate the loss of information caused by the installation of meter triggers at the beginning and at the end of the invoice, the proposed frequency divider contains a generator connected to its input with a coring unit and a control unit for the initial state of the counter triggers, and the generator output is connected to the trigger counter input and To the other input of the said mixer, the “Turn off generator of the control unit is connected to the output of the control unit of the initial state of the meter triggers, and the input“ Turn off the generator of the control unit This is connected to the output of the pulse shaping unit.

The drawing shows the block diagram of the proposed frequency divider.

The divider contains: driver / pulses, trigger counter 2, mixer 3, generator, control unit 5 and node 6 for monitoring the initial state of counter triggers 2.

The operation of the device is as follows.

When supply voltage is applied, the triggers of the counter 2 are set to an arbitrary state. From node 6 of the control, permission is given to turn on generator 4, confirmed by control block 5, since

no input input.

The generator 4 generates pulses until all the triggers of the counter 2 are set to the zero state, and the control unit 6 is activated and generates a signal to prohibit the generator 4, whose operation stops.

With the arrival of the first input pulse on the driver / the last, it generates a signal for 1rig of the counter 2 and at the control node 6, which prevents the generator 4 from turning on for the entire duration of the signal. At the end of the input signal, the node 6 of the control gives permission to turn on the generator 4. The latter generates the clock supplied to

Triggers counter 2 and mixer 3.

 : The number of generator pulses 4, registered by the telemetry system (not shown), is the difference between (HALF coefficient | divider recalculation factor and the number of input and pulses accumulated by the divider by the end of the signal): In order to detect generator 4 pulses at the output sensor 3 From the output signal, their amplitude divisors are chosen to be significantly different. Subject of the Invention A frequency divider for matching a pulse sensor with regy triroi, for example, a telemetry, system containing trig A black counter with a pulse shaper at its input and a mixer, one input of the second is connected to the output of the counter, and the output is connected to the output divider bar, characterized in that, in order to eliminate information loss due to the procedural installation of the estimator in the beginning and in end: counting, it contains a generator with a control unit connected to its input and a node controlling the initial state of the meter triggers, the generator output being connected to the trigger counter input and to another input of the mixer, input “B” (CL10 generator of the control unit connected to the output node controlling triggerovschetchika initial state, and the input "Shutdown control unit of the generator is connected to the output of the ilshulsov.
