Abstract
This correspondence presents a modified lattice structure for IIR filters, which exhibits pleasant scaling properties at no additional computational or memory cost when the reflection coefficients are close to 1. With this structure, the gain at the resonance of a second-order purely recursive section is nearly independent of the bandwidth
