Modified Chebyshev lowpass filters

S. C. Dutta Roy

Open publisher page 5 citations

Abstract

Abstract Simple modifications are proposed for the normal as well as the inverse Chebyshev filter (ICF) for facilitating doubly terminated LC ladder realization, and consequently cascaded active‐RC implementations, for all specifications. The resulting filters are compared with two recently proposed solutions, as well as the competing conventional ones in terms of cutoff slope and the Q of the complex poles. The advantages of the modified filters are discussed. Copyright © 2009 John Wiley & Sons, Ltd.
