Abstract :
Pairs of coincident 
-axis zeros are added to the multiple real root maximally flat (MURROMAF) approximation function for designing sharp cutoff low-pass 
-active filters. Expressions for transfer function and cutoff slope are derived in terms of the order 
, the multiplicity of the real pole 
, the number of pairs of -axis zeros 
and their locations. A design example is also given to illustrate the procedure for finding out the best transfer function.
