Filter synthesis using products of Legendre polynomials

Research output: Contribution to journalArticlepeer-review


Filters derived from Legendre polynomials and products of them are presented using the insertion-loss method. These have properties that lie between those based on the Butterworth and Chebyshev polynomials. Tables of element values for low-pass filter prototypes and curves of attenuation versus normalized frequency are given for design purposes. The extension of the results by frequency transformation to other types of filters is shown by designing a band-pass filter at 1.6 GHz.
