A new design for linear phase fir digital filter with efficient realization

Abstract EN

In this paper, the design of linear phase VlR digital filter using Frequency Sampling method is presented.

Snch design is achieved with a reduction in the maximum .sfoji-barid ripples utilizing optimal iransitiou-bxuit sample value throughout the use of Golden Sreticn search method fur iin^k traosUicn samples, and with aid yf Steepest Dcsccnt method (or double transition samples.

The realisation requirements of such filters are reduced by the we of a new analytic design.

The reduction can be increased to 50% of the whole flU«r Mtrueturc.

Therefore, the dcalgnctl FIR filter offcru global properties, minimum stop-hand, minimum pass-band, average deviation, and reduced structure complexity.
