A device for radio signal multiplexing according a carrier frequency relates to radio engineering and may be used for improving integrity of radio pulses multiplexing as to the frequency carrier in radar systems, radio-navigational and radio monitoring systems. The device incorporates a phase inverter, resonance circuits, an adder, first threshold element and a delay element, phase inverter output through first resonant circuit is connected to first input of the adder, phase inverter input and input of second resonance circuit are connected to device input, output of second resonance circuit is connected to second input of the adder. The device also incorporates a radio signal amplifier, a low-pass filter, a second threshold element, a unit of control signals, video signal amplifier, n-digit binary counter, a set of switches, a unit of digital discriminators. The invention provides decreasing signal/noise threshold ratio due to using advantages of analogue and digital processing of radio signals. |
