A Novel Window Function for Designing FIR Low Pass and Band Pass Filter

Generally filters are used to remove unwanted materials or particles. In signal processing, filter is used to filter the signal with undesired frequency. In most of the communication system, Low pass filters or Band pass filters are used to filter the noise signal from the original speech signal because speech signal has very low frequency compared to noise signal generated from the channel. This paper proposes a new FIR filter in order to get the near ideal response with lowest possible order.
