Explicit formulas for coefficients of maximallyflat FIRlow/highpass digital filters
Ishtiaq Rasool Khan, Ryohji Ohba · Electronics Letters · 2000
New designs of general low/high pass MAXFLAT filters are derived from an available design of halfband lowpass MAXFLAT filters, using a new relationship developed between the tap-coefficients of general and halfband lowpass filters. The presented designs have explicit tap-coefficients formulas, are extremely simple and exactly meet the desired cutoff frequency.
