SU575766A1 - Pulse shaper - Google Patents

Description

one

The invention relates to the field of radio electronics and can be used in signal processing units with pulse phase sensors, such as photoelectric.

A pulse shaper is known that includes a delay device, a trigger, an inverter, and a combination and matching circuit 1.

However, the accuracy of operation of such a driver decreases as the duration and amplitude of the signals change.

The purpose of the invention is to improve the formation accuracy.

This goal is achieved by connecting a pulse driver that contains a limiting amplifier / one output that is connected to the input of the first key and a trigger trigger input, and the second through a delay circuit is connected to the trigger reset input, the trigger output is connected to the second switch. key - with the corresponding input of the adder, entered the integrator and comparator. The integrator input is connected to the output of the summator, and the output of the comparator is connected to the output of the device.

Figure 1 shows the functional diagram of the device; figure 2 - timing charts of his work.

Pulse shaper contains

amplifier-limiter 1, trigger 2, delay circuit 3, adder 4, keys 5 and 6, connected to different sources 7 and 8, integrator 9, comparator 10 and output bus 11.

In the initial state of the trigger 2, the input of the integrator 9 through the key b and the adder 4 is connected to the source b: signal (diagram a in figure 2), pulse from the output of the amplifier-limiter (b in figure 2) tr gyr 2 switches and closes key 6, and opens time with key 5 for time Tj. As a result, the source of the opposite polarity Sc

the key 5 to the integrator input, the voltage at its output begins to vary linearly and over time T (reaches some value Ut KTiGj

The signal delayed by time t by the delay circuit 3 returns the trigger 2
