Description

one

The invention relates to the field of automation and computer technology, in particular to devices for squaring the amplitude of pulsed-modulated voltages.

The quadrants are known that contain a comparator, to one input of which the output of the sawburner generator is connected. The output of the sawtooth generator is also connected to the integrator input, the integrator output is connected via a key to a memory KJujHM capacitor, and the output of the comparator is connected to the control input of the key.

The use of such devices to obtain voltages proportional to the square of the amplitude of the pulse sequence is difficult due to the low speed of its individual nodes.

The purpose of the invention is to expand the field of application of the device.

This is achieved by the fact that a charge capacitor and a stabilized current of its discharge are connected in parallel to the quadrant and connected to the second input of the comparator and through a diode to the input of the device.

FIG. 1 shows the functional scheme of the quad; FIG. 2 shows the timing diagrams of its operation.

The device contains an input unit 1, a driver 2, a diode 3, a trigger) 1, a charge capacitor 5, a discharge current regulator 6, a generator 7 of saw-tooth eg. comparator 8, integrator 9, 10 delay, key 11, memory capacitor 12, output exporter; hetor 13.

The output pulses through the input unit 1 (Fig. 2), and the slip of which has software information, through the diode 3 charges the capacitor 5 of a small e. Bone. as the charge time constant of this kondsor torus is less than the duration (J Hcxouiibix impulses, it is always charged to the value Uj77. At the end of the pulse, the capacitor 5 discharges something; -1z stabilized G discharge current and the voltage on the letter changes linearly by law and by t

This voltage is connected to the riet.UiOMy input of the diode-regenerative com- munity; At the same time, the initial pulse is fed to the input of the former 2, which forms a short pulse, corresponding in time to the 1H1I back edge of the original (Fig. 2, b), which causes the trigger 4 to switch to the second steady state ((} wg. 2, e) , thus launching the linearly-growing N generator U (Fig. 2, e), mod. 2, the Chevny to the second input of the comparator. At the time i of the arrival, the generator Ut. U. has a rotary body (f g 2, c), which, after an additional delay on At (φ g. 2, g with the delay line 10 yomoshi, transfers the trigger to a similar state, preparing the scheme E for processing the following impedance. Directly the output pulse of the napWropa com- plex controls at the input of the key 11 with a recording (4 capacitor 12 of its output. The input for the cucuy enters at the input voltage from the integrator 9, which is 1 volt6 Saw saw) and from the output of the generator 7 W e U, in a parabolic on the f U 10 U Thus, the capacitor 12 is charged every time until its output is U ,. isospocvAj J.P / lo By the time of the times i of operation of the comparator. The time t is determined by the condition of equality “Solving the latter with respect to 1 Therefore, the voltage on the memorized C01 on the covoltage generator is a sianHcaHO ratio; and "K. output 3 () The voltage acquired through the output emitter and the repeater is transmitted to the" next nodes of the common device for processing the current information. The subject of the invention is an American Yuduli Pulsed Pulse () that contains a compresser, to one in which the connection of the output geshfator psiuobrash on the press, the output of the generation of a young bride to the BH-iSiijaTO press. The integrator through the key is connected to the memory of the 4 capacitor 4 output of the comparator connected to the control input of the key, characterized in that, with the aim of expanding the area of the device,. it additionally contains an parallel parallelly switched on-charge capacitor to the current regulator of its discharge,: connected to the second input of the comparator and through a diode to the input 5 of the device.
