Original Abstract

The process of filtering an analog signal removes all frequencies above or below a corner frequency, passing only a band of frequencies, or rejecting a band of frequencies. In the design of analogue filters for the pre-processing of digital signals the filter parameters need to be chosen with respect to the spectral components of the signal being filtered. When digital signals are filtered, however, a totally different set of constraints applies. The paper points out the connection between the choice of cut-off frequency and the shape of the spectrum of processed signal. The design of a new type of filter for data transmission with 4B3T coding is shown. A computer simulation of the chosen filter is performed and the filter spectra prior and subsequent to filtering are compared.
