In general, a direct form realization refers to a structure where the coefficients of the transfer function appear directly as Gain blocks.
In the canonical series cascade form, the transfer function is written as a product of first-order and second-order transfer functions.
In the canonical parallel form, the transfer function is expanded into partial fractions.
For a given digital filter, the canonical forms describe a set of fundamental operations for the processor.
