Editor’s note: I came across this excellent tutorial article on Digital Filter Design and I thought it would be an excellent guide for novices as well as seasoned veterans. I want to thank William H.

Abstract: We present here the sensitivity of classical filter transfer functions that are polynomial approximations to the ideal brick-wall magnitude response. The transfer function is decomposed into ...

Digital signal processors (DSPs) continue to receive a great deal of attention in new product design. For example, digital filter design reflects the importance of understanding and using this ...

Abstract: We present a flexible and dynamically programmable optical filter based on an all fiber Michelson Gires-Turnois interferometer (MGTI). Arbitrary filter transfer functions can be accomplished ...

Small-signal analysis of switching dc-dc converters determines their specific transfer functions, for example, for stability analysis or design of a proper input filter. Transfer functions of interest ...
