Abstract
A new Chebyshev-like low-pass filter approximation is proposed for which the order is always odd and hence there is no problem for doubly terminated LC ladder realization. Flexibility of shaping the response and lower Q values of complex poles appear to be the major advantages of the new approximation as compared to the normal Chebyshev filter.
