Sensitivity properties of resonator-based digital filters
Gábor Péceli · IEEE Transactions on Circuits and Systems · 1988
The sensitivity properties of the recently introduced common structure for recursive discrete transforms are investigated. This structure is based on digital resonators in a feedback loop. It is shown that this structure has very nice sensitivity properties near to the resonator pole frequencies, and that by locating the resonator poles properly, even the 'passivity' of the feedback loop can be easily guaranteed.>
