A new spectral efficient window for designing of efficient FIR filter

By using the concept of Bartlett-Hanning (MBH) window, a new window is proposed which may be referred as "Proposed Window". It is found that with parameter a = 0.0625, this window can attain a slightly reduced half main lobe width as compared to the Blackman window, a maximum side lobes level (MSLL) of -66 dB which is approx. -8 dB better as compared to Blackman window and maximum first side lobes level (FSLL) of -75.4 dB which is approx. -18 dB better as compared to Blackman window. The Proposed Window is also analyzed on other useful parameters with conventional window. Here we are designing digital finite impulse response (FIR) low pass filter based on the Proposed Window and it is found that the designed FIR filter is more efficient as compared to the conventional FIR filters.
