SIMULATION DEVICE OF NOISE SUPPRESSION SYSTEM WITH FREQUENCY PREDISTORTIONS Russian patent published in 2015 - IPC G11B20/24 

FIELD: measurement equipment.

SUBSTANCE: simulation device of a noise suppression system with frequency predistortions introduces in each channel the rise of level of high-frequency components of the signal at transmission or recording by means of in-series connected adjustable components: the first amplifier and a high-pass filter, the output of which is connected to one of the inputs of one of the adders, the other input of which and the amplifier input are an input for supply of a signal with further correction at reception or reproduction by means of the corresponding adder, to the inputs of which there are connected outputs of the adjustable amplifier and a low-pass filter, the combined inputs of which are inputs for reception of the transmitted or recorded signal. The simulation device of the noise suppression system also includes a multiplexer, the input of which is connected to corresponding outputs of channels.

EFFECT: enlarging functional capabilities of the device.
