This paper presents an efficient method for designing FIR filters by combining the frequency-response masking (FRM) approach with the WLS-Chebyshev method. With the proposed method, the specifications for the base filter in the FRM approach can be relaxed. This is accomplished based on the ability of the WLS-Chebyshev method for finding a good compromise between the minimum attenuation and total energy within the filter's stopband. A typical design performed with the proposed method is included
