From Ashtabula to Xenia and all points in between, Ohio's anglers and naturalists will enjoy this handy field guide to help them identify 65 species offreshwater fish. Whether spotted bass in the south, sauger in the north, or any number of colorful sunfishes from ponds and creeks, this guide describes any species likely to be caught by hook-and-line.The noted diagnostic characters and beautiful color illustrations will prove an indispensable aid for identification. Included are notes on preferred habitat and favorite baits for landing each species. This 12-panel guide conveniently folds up in to a packet narrow enough to fit in a back pocket, glovebox, or tackle box yet sturdy enough to stand up under repeated use durable lamination also makes it waterproof.
The function of a filter is to transform a signal into another one more suit- able for a given purpose. As such, filters find applications in telecommunica- tions, radar, sonar, remote sensing, geophysical signal processing, image pro- cessing, and computer vision. Numerous authors have considered deterministic and statistical approaches for the study of passive, active, digital, multidimen- sional, and adaptive filters. Most of the filters considered were linear although the theory of nonlinear filters is developing rapidly, as it is evident by the numerous research papers and a few specialized monographs now available. Our research interests in this area created opportunity for cooperation and co- authored publications during the past few years in many nonlinear filter families described in this book. As a result of this cooperation and a visit from John Pitas on a research leave at the University of Toronto in September 1988, the idea for this book was first conceived. The difficulty in writing such a mono- graph was that the area seemed fragmented and no general theory was available to encompass the many different kinds of filters presented in the literature. However, the similarities of some families of nonlinear filters and the need for such a monograph providing a broad overview of the whole area made the pro- ject worthwhile. The result is the book now in your hands, typeset at the Department of Electrical Engineering of the University of Toronto during the summer of 1989.
