Abstract
The performance dependence of a computationally efficient digital quad rature demodulator on the number of filter coefficients for various fi lter design methods is investigated. It is shown that an image rejecti on ratio exceeding 100 dB can be achieved using a pair of finite impul se response filters having six and five nonzero coefficients, respecti vely.
