The object of the invention is parametric pass-band filter based on parametrons. To obtain a narrow U-shaped regulable amplitude-frequency characteristic, the source of the filterable signal is connected to the circuits of pumping of two parametrons with amplitude-frequency characteristics shifted onto the pass-band, the output of the first parameter is connected through an inverter to the first input of the matching circuit. The output of the second parametron, the amplitude-frequency characteristic of which is shifted into the region of the lower frequencies, is connected to the second input of the matching circuit coincidence circuit.
