SU402152A1 - PULSE DISTRIBUTOR - Google Patents

Description

one

The invention relates to computing technology.

Pulse distributors are known that contain a switching trigger with two clock frequency channels, a coincidence circuit, an auxiliary pulse distributor, and output triggers with a counting input.

Such distributors do not give the possibility of obtaining a series of overlapping pulses with an arbitrary shift, which is necessary with parallel control of the operation of a number of devices of different systems.

The purpose of the invention is the formation of sulfur overlapping shifted pulses that satisfy the condition T (p-1) A /, where T is the duration of a single pulse, n is the number of pulses in a series. A / is the shift between two pulses (may vary depending on the specific application conditions).

The proposed valve is characterized in that the first channel of the clock frequency is connected to a single input of the switching trigger, the output of the latter is connected to the first input of the coincidence circuit, and the second drop of the clock frequency is connected to the second input of the coincidence circuit, the output of which is connected to an auxiliary pulse distributor (for example, shift register units), the n outputs of which are connected to the counting inputs of the n output triggers, whereby the p.-ny output ps of the impulse distributor of pulses are simultaneously connected1, not 11 with zero input switching trigger house.

Functional diagram of the device prvedepa in the drawing.

The distributor co.p., switches commute trigger 1, the scheme coincides :; 2, auxiliary distributor of pulses 3 and n output triggers 4.

In the initial state, the auxiliary distributor 3H triggers 1, 4 are set to zero. The distributor start impulse, which arrives at pin 5, synchronously with the first pulse and second clock frequency channels, sets the commutation trigger 1 to one, and the remaining triggers to zero. The pulses of the second channel with the period Ar through the open match circuit 2 are fed to the input of the auxiliary pulse distributor 3 with the number of outputs equal to the number of pulses in the series. The signal "running around the outputs of the pulse shifter with a shift triggers the output triggers 4, converting them to one state, the nth output pulse of the auxiliary distributor returns the commutator trigger 1 to the initial zero state.

Thus, a series of overlapping shifted

pulses satisfying condition 7 (n-1) D.

To form a new series, you need to manually or automatically submit a launch trigger to spike 5.
