用窗函数法设计FIR数字滤波器。包括：1.矩形窗2.三角窗3.汉宁窗4.海明窗5.布拉克曼窗6.凯泽窗等(FIR digital filter design with a window function method. Including: a rectangular window. Triangular window. Hanning Hamming window, Blackman window and Kaiser window)

Designs a linear phase FIR lowpass filter such that it: - minimizes the filter order - has a constraint on the maximum passband ripple - has a constraint on the maximum stopband attenuation (This is a quasiconvex problem and can be solved using a bisection. minimize filter order n s.t. 1/delta <= H(w) <= delta for w in the passband |H(w)| <= atten_level for w in the stopband where H is the frequency response function and variable is the filter impulse response h (and its order/length). Data is delta (max passband ripple) and atten_level (max stopband attenuation level). )
