An orthogonal detector and the orthogonal demodulator and the sampling orthogonal demodulator which using the orthogonal detector

摘要

The present invention is orthogonal to remove low-frequency components in the orthogonal detector and the quadrature demodulator and the sampling orthogonal relates to a demodulator pass through a first high pass filter passes the 111 first and inphase 2 to remove the low-frequency component by the high-pass filter using the same 112 generating a sum of the signal to a multiplier 122 to a quadrature phase error between the output of the orthogonal signal and phase signal of the orthogonal demodulator to enable the detection of the quadrature phase error due to a signal to remove high-frequency components in the low-pass filter 131 of the It provides a technique for detecting a.
