โœฆ Synopsis

Trahan, R. E., Jr., Grosz, F. B., Jr., and Griffin, S., An Improved Method for Design of Recursive Digital Filters Using Optimization, Digital Signal Processing 5 (1995) (167-175).

With the increased capability of today's personal computers ( (\mathrm{PC}) ) and software packages, it often is advantageous to formulate engineering problems in such a way as to take full advantage of these resources. In this paper a new approach to recursive filter design is presented which takes advantage of a popular spreadsheet program and a simple formulation of an optimization problem. No code must be written other than the formula definitions in a spreadsheet. Explicit derivatives are not needed and full interaction with the optimization process is possible, including graphical information. Results are given for an eighth-order filter and these are compared to previously published designs. (\quad x_{1995}) Academic P'ress, Inc

This paper proposes a narrowband filter, which is a finite impulse response (FIR) filter where the phase response exhibits a constant phase-linear characteristic, independently of the center frequency, and the execution format is a sum of stable recursive filters. The optimal design of the different
