Impulse Response of Universal Maximally Flat FIR Filters

Impulse Response Coefficients of Universal Maximally Flat FIR Filters ¹

Group delay parameter d is fully adjustable. It is treated as a rational number and expressed as a fraction.
Special care is taken to retain the accuracy throughout the computation and obtain precise results in the form of fractions.
As the computation is performed in intgers, and in consideration of the limited integer length in this implementation, care should be exercised when the numbers involved internally approach (2^{53}-1).
