Abstract :
Multidimensional finite impulse response (FIR) filters designed by the McClellan transform can be implemented efficiently by the direct transformed structure, transpose direct transformed structure, cascade structure, Chebyshev structure, and reversed Chebyshev structure. Peak scaling and section reconfiguration are provided here to modify the cascade structure realization. The modifications result in a reduction in the output roundoff noise power and the number of operations required
