Abstract :
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.
