FIELD: engineering of signal receivers with absolute phase manipulation. ^ SUBSTANCE: one input of phase detector is connected to linear portion of receiver, and another input is also connected to linear portion receiver, but through narrowband (~300Hz) filter, phase shifter for 90, limiter amplifier, while narrowband filter is also connected to linear portion of receiver. In construction of receiver device phase detector has no reverse operation, because its bearing oscillation is formed by component of bearing frequency of input phase manipulated signal, which for aforementioned angle of manipulation is present in signal. ^ EFFECT: increased interference resistance of signals receipt with absolute phase manipulation. ^ 1 cl, 1 dwg |
