The invention relates to a pulse technique and can be used in simulating automatic control systems. The purpose of the invention is to enhance the functionality of a random process generator by generating nonlinear composite random signals.

FIG. 1 shows a structural electrical circuit of a random process generator in FIG. 2 - time diagrams of his work.

The random process generator (Fig. 1) contains a random voltage generator 1, the output of which is connected to the inputs of the first and second memory blocks 2 and 3, the outputs of which are connected to the inputs of the first and second keys 4 and 5, respectively, the outputs of which are connected to the integrator input 6, the output of which is connected to the input of the comparator unit 7, a clock pulse generator 8, a trigger 9, a NOT element 10 whose input is connected to the control input of the first key 4., to the control input of the first memory block 2 and the generator output 8 of clock pulses , entrance to Secondly, it is connected to the control input of the integrator 6 and the output of the flip-flop 9, the input of which is connected to the output of the comparator unit 7. The output of the element NOT 10 is connected to the control input of the second memory unit 3 and the control input of the second key 5.

The random process generator works as follows.

By the Start signal supplied to the installation input, to the unit of the trigger 9, the latter is set to the one state (Fig. 26). "The signal from the output of the trigger 9 zeroes the integrator 6 and enables the generator of 8 clock pulses, the signal from the output of which (Fig. 2c) goes to the control input of the first memory block 2 and fixes the instantaneous value of the random voltage to the last front (Fig. 2a) from the generator 1 of random voltages. The magnitude of the fixed voltage value is proportional to the rate of increase of one of the sections of the composite random process.

3 of the memory, the next instantaneous random voltage is proportional to the rate of change. signal on the adjacent part of the implementation of the composite random process i

The integration of the voltage detected in memory block 2 begins at the leading edge of the pulse of the generator 8 and is interrupted at the moment the first key 4 is opened. The opening occurs after the end of this pulse. By the time the first key 4 is opened, the next instantaneous value of the random voltage c is located in the memory block 3. 1 random voltage generator.

The integration of this voltage by the integrator b is made during the action on the equalizing input of the second key 5 of the inverted signal from the generator 8 clock pulses. At this time, a new instantaneous value of the random voltage is recorded in the first memory block 2. The sequential arrival at the input of the integrator b of the voltage values from memory blocks 4 and 5 ensures the continuous generation of each implementation of a random composite process.

The generated implementation (Fig. 2d) ends when the voltage at the output of the integrator 6 reaches a certain predetermined value, installed in the comparison unit 7, the signal from the output of which sets the trigger 9 to the zero state.

The next implementation of the random process begins after the signal is given. The start-up at the input of the unit into the trigger unit 9.
