In published weighted least square method, the weighting matrix has no connection with the targeted filter, which limits the application of this method. To overcome this drawback, this article presents a novel meliorated weighted least square method with variable parameters for digital filter design. In the new method, the targeted filter is used to form the weighting matrix with two parameters. Through the parameters, the attenuation of stop band of the filter is able to be controlled.
