Approximated Fractional Order Chebyshev Lowpass Filters
We propose the use of nonlinear least squares optimization to approximate the passband ripple characteristics of traditional Chebyshev lowpass filters with fractional order steps in the stopband. MATLAB simulations of (1+α), (2+α), and (3+α) order lowpass filters with fractional steps from α = 0.1 t...
