Abstract
We introduce a solution to lowpass filters with multiple pairs of transmission zeros at two distinct frequencies in the stop-band. The filters derived are subjected to the criterion of minimum weighted least-mean-square error in any interval of interest in the passband. It is shown that the maximally flat sharp-cutoff filters are special cases of this new approximation.
