Choosing a filter structure: component sensitivity and design-for-testability

The choice of filter structure and its effects on circuit test and implementation sensitivity are examined. Preliminary results have shown the lattice structure to often have a low relative structure-algorithm time constant, making it a strong candidate for implementation in many applications. Since the parameters of such systems can be easily determined from input/output data, and the system design is insensitive to the design parameters, such structures can be used to advantage where design-for-testability is needed
