Design of Chebyshev-type IIR filters with approximately linear phase characteristics

Digital filters with a linear phase characteristic are needed in many applications for signal processing. In this paper, design of a Chebyshev‐type IIR filter with approximate linear phase characteristics in the passband is described. First, it is shown that a flat stopband can easily be realized by...
