Another algorithm for converting a low-pass function into bandpass form
Article Abstract:
A new algorithm is described that enables the generation of the values of the coefficients of a bandpass filter from a low-pass transfer function. The algorithm uses a recurrence easily programmed by synthetic polynomial multiplication. Slightly more than one array is required to hold the low-pass input, one array is required to hold the resulting bandpass coefficients, and there is minimal loop overhead. Programming the recursion process is described.

An improved algorithm for low-pass to bandpass transformations
Article Abstract:
An algorithm is developed that offers excellent accuracy, no scaling problems, and superior computational performance in performing standard low-pass to bandpass transformations. Improved computational efficiency is a consequence of the use of a recursion relation. The generality of the algorithm allows any number of zeros and poles in the transfer function. Details of the development and validation of the algorithm are described.

A class of bandpass and bandstop Butterworth digital filters
Article Abstract:
A class of bandpass and bandstop Butterworth digital filters is presented that are simple to implement using existing software for low-pass and high-pass filters. They can be used to good advantage in a number of signal processing applications. They are realized as a cascade of second-order sections and are amenable to hardware implementations in fixed-point as well as floating-point environments.
