Description

one

The invention relates to measuring and computing techniques and can be applied in analog and discrete automatic systems and computing complexes, instruments and automation devices to obtain a set of functions from several continuous positive electrical signals limited by the upper frequency of the spectrum or positive signals, abruptly varying at discrete times.

The purpose of the invention is the expansion of the class of tasks.

The drawing shows the functional diagram of the computing device

The computing device contains the chip integrator 1-4, the first and second keys 5 and 6, the comparator 7.

The device works as follows.

Voltage sources of electrical signals of input positive variables U, Ugji. U & xa are connected to the first, second and third inputs of the device, respectively. Keys 5 and 6 are at the same time in the open state and through them permanent signals are received by integrator 2 and 3, respectively.

The signals at the outputs of the integrators increase linearly until time t, determined by the triggering of the comparator 7 and the release of keys 5 and 6, after which these signals remain constant.

Thus, with the same constant time integrators 1-4 their output voltages are equal
