A Multiple-Exchange Algorithm for Complex Chebyshev Approximation by Polynomials on the Unit Circle

This paper presents a generalization of the Remez multiple-exchange (ME) algorithm for solving complex Chebyshev approximation by polynomials on the unit circle. The difficulties of implementing the ...

Zero offset active lowpass filter, part 3

The circuit in Figure 1 was given to me some while ago as a three-pole, active 1 dB Chebyshev lowpass filter. I never confirmed that its transfer function complied with the Chebyshev polynomial, but ...

6.5 to 23 MHz 3rd order low pass filter

Low pass filter (3rd order Chebyshev filter) is based on the gyrators with cut-off frequency adjustment in wide range (6.5…23 MHz ). There are two mod ...

Two identities involving the integral of the first kind Chebyshev polynomials

In this paper, we use the algebraic manipulations and the properties of Chebyshev polynomials to obtain two interesting identities involving the power sums of the integral of the first kind Chebyshev ...

Zero offset active lowpass filter, part 4

A little while back, I presented a nearly-zero-offset Chebyshev lowpass filter. Two comments were made that must have seemed valid to their authors, but they were not. Figure 2 This change adversely ...
