Claims

If there are signals with a frequency f on the input buses 16, 1, they pass through the input filters 3, 5 tuned to the frequency f | and are detected by the detectors 7, 9. The signals from the detector output go to a controlled oscillator II, which The presence of two signals generates broadband noise. A part of the spectrum is formed from it with an average frequency ff, allocated by the output filter 13 tuned to the frequency f |, and fed to the adder 15, the output of which is the output of the device. In this way, the device performs a logical AND operation. If there are signals at one or both input tines with an average frequency fo, they pass through the input filters 4, 6 tuned to the frequency f, are detected by the detectors 8, 10. after which they are sent to the controlled generator 12. which generates broadband noise at the presence of one or two input voltages. A part of the noise spectrum is allocated by the output filter 14, the average tuning frequency of which is 1, and is fed to the input of the adder 15. If the filters with a resonant frequency ti are swapped with filters that have a medium frequency (o, the device will perform a logical OR operation. In a number of cases, it is possible to simply switch the filter tuning frequency, which is equivalent to switching the logic function from AND to OR and vice versa. Additional information to the output signal can be entered when modulating the output filters by bandwidth. Mula of the invention.
