THRESHOLD DEVICE WITH THRESHOLD NOISE STABILIZATION Russian patent published in 2020 - IPC H04B1/10 

FIELD: physics.

SUBSTANCE: invention relates to the reception of signals, in particular to the equipment for extraction of signals from noise. Into threshold device with noise stabilization of threshold, which contains threshold device with signal and control inputs, standard pulse generator and a noise automatic threshold adjustment circuit (ATAC) connected between the output of the standard pulse former and the threshold control circuit associated with the threshold device control input, introduced is a threshold reset circuit connected to the threshold device and controlled from the clock generator output, by the output associated with the clock cycle counter, at the output of the pulse shaper there is a key, controlled from the clock counter output, and an adder whose output is connected to the threshold control circuit, its information input is connected to the standard pulse generator output, the control input is connected to the clock counter output. Threshold control circuit may be equipped with circuit of threshold level increase in times connected with clock counter, where is threshold increase factor required to provide preset frequency of noise tripping in operating mode; f_p is steady-state noise operation frequency; f_lt is a given frequency of noise tripping in operating mode; f₀ is zero-level noise excess frequency. Level increase circuit may be made in the form of an attenuator with an attenuation coefficient introduced at the threshold device input.

EFFECT: technical result of the invention is to reduce the time for reaching the operating mode.
