DIGITAL FILTER STRUCTURES AND QUANTIZATION EFFECTS

Hardware implementations require signiﬁcantly more logicthan ﬁxed-point implementations; Software implementations require signiﬁcantly more operations so run much more slowly on the same processor Floating point arithmetic although much harder to implement poses less of a problem to the digital ﬁlter designer than ﬁxed point

How to implement a transfer function d(z) as a “network” of primitive arithmetic operations?
The first consideration is how to implement a transfer function D(z) as a “network” of primitive arithmetic operations: add, multiply, delay. For software realizations, the network corresponds to a flowchart of the filter algorithm. For hardware realizations, the network describes the actual circuit elements and their interconnection.
Are parallel IIR filters easier to deal with?
Parallel IIR filters are a bit easier to deal with, because the issue of pairing and ordering does not arise. Jackson concluded that the total signal-to-quantization noise of the parallel form is comparable to that of the best pairing and ordering of the cascade form.
How does network structure affect the performance of a digital implementation?
For software realizations, the network corresponds to a flowchart of the filter algorithm. For hardware realizations, the network describes the actual circuit elements and their interconnection. We will see that the performance of a digital implementation is affected substantially by the choice of network structure. 2N + 1 multipliers.
