INTRODUCTION
Digital filtering is one of the most powerful tools of DSP. Apart from the obvious
advantages of virtually eliminating errors in the filter associated with passive
component fluctuations over time and temperature, op amp drift (active filters), etc.,
digital filters are capable of performance specifications that would, at b
