WebJun 28, 2016 · Summary. When using the window method to design an FIR filter, we start from filter specs ωp ω p, ωs ω s and δ δ. Having δ δ, we can choose the appropriate window type from Table I. We can use the transition band, ωs −ωp ω s − ω p, as an estimate of the required main lobe width and therefore find the window length from Table I.
