A method is presented for determining the transfer function of low-pass filters whose attenuation shows a Chebyshev characteristic in the stopband and whole phase or delay time can __-_2 for n even be specified independently of the aforementioned attenuation properties. The transfer functions may be realized by simple ladder networks. In order to obtain, as far as possible, transformerless circuits, the transfer function to be determined has a pole at infinity.
