Thus, describing the claimed generator dimensionless equations (3) and describes the prototype dimensionless equations (6) differ only by a nonlinear function S(y-x) and h(y-x).In the composition of the dimensionless current-voltage characteristics of S(y-x) we can distinguish M+N+1 segments h

(as 2kc - a constant that does not depend on the dimensionless time), we get the system

which is no different from the system of dimensionless differential equations (6), describing the dynamics of the prototype as the function

In certain known properties of the prototype, the values of the coefficients,,,k each such system of equations determines the movement of the operating point within all three areas of its segment. Therefore, the working point located on a common lateral area adjacent segments may over time re the points moves within all segments of the function S(y-x), that ceteris paribus increases the size of a strange attractor in the inventive generator approximately

As describing the claimed generator local system of dimensionless equations (10) is identical to the dimensionless equations (6), describing the prototype, the data values of the coefficients,,,k is known from the properties of the prototype. Therefore, the values of the physical parameters of the proposed generator giperbolicheskikh oscillations are selected from the ratios of the(4), (7), (8).When the identity of all transistors nonlinear device with negative conductivity is given in the claims the volt-ampere characteristic, if

Reducing a value of the voltage u, is applied to a nonlinear device with negative conductivity, everything is repeated in reverse order.High temperature stability of the generated giperbolicheskogo signal due to the fact that the equivalent negative conductivity linear device with negative conductivity and current-voltage characteristic of the nonlinear device with negative conductivity is practically not depend on the parameters of the transistors due to the mutual compensation of the emitter resistances of the transistors 23 and 25, 24 and 30, 26 and 27, 31 and 32 in each of the impedance Converter.Giperalgeticheskie fluctuations in equations (10), characterized by movement of an operating point within all three areas of each segment of volt-ampere characteristics of a nonlinear device with negative conductivity occur, in particular, when10,=0,5...0,7,1,5,-0,2, k-15.If you acceptC1=100 nF, giperbolicheskie fluctuations in the

In the case M=1, N=0 output currents of the first 20 and second 21 current generators of the first and fourth two-port and the output current of the second generator 21 current of the second quadrupole approximately equal to 0.8 mA. Output currents of the first 35 and second 36 generators converters impedance included in the first and fourth two-port, equal to 1.6 mA. Output currents of the first current generator 20 of the second quadrupole and the second generator 21 current of the third quadrupole is equal to 6.4 trehpolyusny, equal to 8 mA.In the case M=N=2 device with negative conductivity contains six four. Output currents of the first 20 and second 21 generators of two equal to 0.8 mA. Output currents of the first 35 and second 36 generators converters impedance equal to 1.6 mA.To the generator of chaotic oscillations, non-linear device with negative conductivity, containing six two-port, electronic reconstruction from the case M=N=2 to the case M=1, N=0, it is necessary to increase the output currents of the first 35 and second 36 generators DC Converter impedance, part of the third quadrupole, up to 0.8 mA, output currents of the first current generator 20 of the fourth quadrupole and the second current generator of the fifth quadrupole - to 9.6 mA output currents of the first 35 and second 36 generators DC Converter impedance, part of the fifth four-terminal network, - to 11.2 mA.Thus, the proposed generator giperbolicheskikh oscillations differs from prototype and analogs, which provides additional, in comparison with them, the ability to control parameters generated giperbolicheskogo signal by changing the geometry of the strange attractor is Timothy.
