Abstract
The present invention provides a bi-directional low pass filtering method and apparatus for attenuating out-of-baseband components of data transmitted from an encoder to a decoder over a transmission medium. In one embodiment of the present invention, the bi-directional low pass filtering apparatus includes a Chebyshev filter that has a first phase response. This Chebyshev filter is coupled to a phase correction circuit, which has a second phase response. This second phase response of the phase correction circuit is designed to oppose the first phase response in order to offset variations in group delay in the data due to the Chebyshev filter.
