FUNCTIONAL GENERATOR Russian patent published in 2017 - IPC H03B27/00 

FIELD: electricity.

SUBSTANCE: functional generator contains an oscillator 1, the first 2 and the second 3 square-law devices, the first 4 and the second 5 multipliers and an adder 6, which output is connected to the first input of the second multiplier 5, which second input is connected to the second output of the oscillator 1, which first output is connected to the input of the first square-law device 2, the second square-law device 3 is connected between the output the first square-law device and the second input of the adder 6. The first, the second and the third outputs of the functional generator are connected to the first output of the oscillator 1, to the output of the second multiplier 5 and the second output of the master oscillator 1 respectively, the control input of which is connected to the control line of the functional generator. The fourth input of the adder 6 is connected to the reference voltage bus line, the calculator of the module 7 and the inverter 8 placed between the output of the first square-law device 2 and the third input of the adder 6 are additionally introduced, and the calculator of the module 7 is connected between the output of the first multiplier 4 and the first input of the adder 6.

EFFECT: reduction of harmonic signal nonlinear distortion.
