Coefficient sensitivities of cascaded lattices at zero frequency
Yrjo A. Neuvo, Olli Simula · IEEE Transactions on Acoustics Speech and Signal Processing · 1976
Expressions for the coefficient sensitivities of cascaded digital lattices introduced by Itakura and Saito and further developed by Gray and Markel are calculated using chain parameters. It is shown that a cascade of lattices with ε = +1 exhibits zero coefficient sensitivities at zero frequency.
