Abstract :
In this paper, we use the Fourier series algorithm in the design of filter. But we don´t use the window functions. Instead, we use the genetic algorithm (GA) on the discrete cosine transform (DCT) of a given band-pass characteristics. This paper´s method is useful on an ASIC equalizer (filter) design through the number of the coefficient is reduced. Indeed, an example shows that the proposed method can offer 1/2 decreased high order Fourier coefficients for a given band-pass characteristics. These coefficients are compressed in 1/2
