DEVICE TO CALCULATE VALUES OF SIGNAL AND NOISE AMPLITUDES Russian patent published in 2013 - IPC G01R23/00 

FIELD: radio engineering, communications.

SUBSTANCE: device to calculate values of signal and noise amplitudes, comprising the following serially connected components: an antenna, a mixer, an intermediate frequency amplifier (IFA), and also a heterodyne, the output of which is connected with the second input of the mixer, the antenna input is the device input. The device comprises the following serially connected components: the first unit of signal processing, the first analogue-to-digital converter (ADC) and a calculator of signal and noise amplitude values, the output of which is the device output, serially connected the second unit of signal processing, the second ADC, the output of which is connected with the second input of the calculator of the signal and noise amplitude values, inputs of the first and second blocks of signal processing are combined and connected with the IFA output. At the same time the first unit of processing comprises serially connected an accumulating circuit and the first amplitude detector, and the second processing unit represents the second amplitude detector.

EFFECT: increased accuracy of signal amplitude assessment with availability of noise.
