The use of signal processing for power quality applications is not a new idea as several researchers have used signal processing for more than a couple of decades. In the past few years however there has been a renewed interest in exploiting signal processing techniques for power quality measurements and analysis. The rationale for such enthusiasm is that signal processing techniques indeed provide meaningful and valuable information about voltage and current signals. As a result a better understanding of time-varying time-invariant and transient behavior of power systems can be obtained. By looking into the development offered by signal processing techniques to the analysis of other well-known signals such as speech and image
