Digital Video BroadcastingTerrestrial (DVBT) is an international standard for digital television
services. Orthogonal Frequency Division Multiplexing (OFDM) is the core of this technology. OFDM
based system like DVBT can handle multipath fading and hence it can minimize Inter Symbol
Interference (ISI). DVBT has some limitations too namely large dynamic range of the signals and
sensitivity to frequency error. In order to overcome these limitations DVBT receivers should be optimally
designed. In this paper we address the issues related to optimal DVBT receiver design. There of several
signal processing units in a DVBT receiver. A lowpass filter is one of them. In this paper, we consider
some classic filters namely Butterworth, Chebyshev, and elliptic in the DVBT receiver. The effects of
different filters on the performances of DVBT receiver have been investigated and compared in this
paper under AWGN channel condition
