Description

one

The invention relates to the field of pulsed technology.

A known parabolic pulse generator containing a dual thermostated semiconductor trnod N two operational amplifiers, the signals from the outputs of which are fed to the inputs of the adder.

However, the known generator has a complicated circuit due to the need for thermostatic control of the semiconducting triode.

According to the main author. swith No. 473182 is a parabolic shaped pulse generator, which contains a master pulse generator, waiting for a nilo voltage generator, connected to the output of a master pulse generator, the outputs of which are connected via an integrator to the inputs of the adder.

The disadvantage of such a generator is the impossibility of changing the shape of parabolic nmiuls.

In order to alter the shape of the parabolic pulses, a further stand-by generator of impulses is inserted into the proposed device, connected between the output of the master pulse generator and the input of one of the waiting sawtooth voltage generators.

The drawing shows a structural electrical circuit of the proposed generator.

The generator contains a setting generator of 1 pulses, a waiting generator of 2 sawtooth voltage, a waiting generator of 3 pulses, an advanced generator of 4 sawtooth voltage, integrators 5, 6, adder 7. Output signal g1 is removed from output 8. The geerator works as follows. Oscillator 1 generates straight carbon nanometers, the duration of which can be adjusted. The front edge of the pulse from generator 1 is started by generator 3, which generates a rectangular pulse, the duration of which can also be adjusted. The durations of the nmiuls are adjusted independently. Rectangular pulses control the generators 2 and 4, which generate pulses of a south-facing sawtooth pattern, the duration of which is equal to the length of the scorch of nm pulses H having the same torque. These pulses are integrated by integrators 5 and 6, resulting in a VBF. Parabolic impulses are formed by an adder 7 out of the narabol branches. The independent variation of the durations of the n-mopar impulses allows a smooth transition from impulses, the naming form of the descending branch of a parabola, through a pulse, which is a complete symmetrical parabola, to an imulse having the form

rising branch parabola. So, for example, if the duration of the pmiuls e of the generator 3 is equal to zero, the illumination having the shape of a nisyadyunlyy parabola branch will be geyerted, if the durations of the Nmulsovs of the 1 n 3 generators are equal, impulse, nmeyush.ny form of the ascending branch of a parabola. If other coOTHOHieHHHx durations are made of irregular and pulsating, the shape of the output pulse will give an intermediate look. Thus, independent regulation of rectangular pulse pulses allows the shape of the output parabolic pulse to change in a wide range.
