Abstract :
The modified inverse Chebyshev function exhibits progressively diminishing ripples in the stopband. The modified inverse Chebyshev function can be realizable using the doubly-terminated ladder network for the order n even or odd. Besides the doubly-terminated ladder network realizability, lower pole-Q values of the modified inverse Chebyshev function are accountable for improved time delay characteristic, preferable time domain performance, and low pole-Q sensitivity as compared with the classical inverse Chebyshev function
