Abstract
The calculation of digital filter quantization noise can be facilitated through the solution of the Lyapunov equation 
[1]. This method, however, only includes the contributions from the quantization which occurs at the inputs to time delays, that is, at the "storage nodes" of the filter. This letter shows how the method can be extended to include the contributions at the other nodes, the "signal nodes."
