THE WIGNER DISTRIBUTION - A TOOL FOR TIME-FREQUENCY SIGNAL ANALYSIS
In this second part of the paper the Wigner distribution is adapted to the case of discrete-time signals. It is shown that most of the properties of this time-frequency signal representation carryExpand

Some Considerations on the Design of Adaptive Digital Filters Equipped with the Sign Algorithm
In this paper we present some tools that can be helpful in the design of adaptive digital filters operating with the so-called sign algorithm. Although theoretical results with respect to theExpand

Necessary and sufficient conditions for the absence of overflow phenomena in a second-order recursive digital filter
Due to adder overflow, different stationary output signals can be obtained from a digital filter for the same input signal. This phenomenon is discussed for a second-order recursive digital filter,Expand

Design of Smearing Filters for Data Transmission Systems
In this paper, we introduce a new approach to design smearing and desmearing filters for data transmission systems to suppress pulse-like disturbances inserted in the communication channel. OurExpand

First-time-right si but to the right specification (keynote address)
With the increasing complexity of today’s (and certainly tomorrow’s) integrated systems, the real design challenge has shifted from making first-time-right silicon to making a first-time-rightExpand
