Behavioral Specification of a Circuit Using SyncCharts: A Case Study
In this paper we propose a high-level description of the behavior of digital systems. Behaviors are specified with a graphical synchronous model: “SyncCharts”. SyncCharts supp...

A recursive method for the approximation of LTI systems using subband processing
Using the subband technique, an LTI system can be implemented by the composition of an analysis filterbank, followed by a transfer matrix (subband model) and a synthesis filterbank...
