Abstract
The accuracy of digital quadrature demodulation can be improved by optimizing the matching of the inphase and quadrature channel frequency responses. It is shown that an image rejection performance exceeding 100 dB can be achieved using finite impulse response filters having as few as eleven nonzero coefficients.<>
