Abstract :
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
