Abstract
An efficient algorithm for real-time digital quadrature demodulation is presented. It can be implemented with a pair of quadrature highpass finite impulse response filters and decimators. The filters are derived from a quarter-band lowpass filter prototype through the use of appropriate transformations. The implementation of the algorithm using VLSI technology is discussed
