Digital filters are widely used in many digital signal processing applications. Therefore, digital filtering is one of the basic needs of digital signal processing. This paper introduces a new coupled window by adding of two windows, known as Kaiser and Hanning, for the design of finite impulse response (FIR) digital filters. The quality of the proposed window is analyzed in terms of window spectral parameters, main-lobe width (MLW) and side-lobe amplitude, and then compared with other windows, namely Kaiser and Hanning. Results show that the proposed window can provide 1.5 to 4 dB side-lobe amplitude and smaller MLW than other windows for fixed window length (M=51). Equivalent Noise Bandwidth (ENBW) calculated also gives better results i.e. 1.05. Application example for the performance analysis of the proposed window in digital filter design confirms that the window can exhibit a better filtering performance by providing smaller minimum stop-band attenuation (As) for fixed filter length (M=51) compared to Kaiser and Hanning window.
