| Abstract: |
| In this paper,according to the relationship between the magnitude response of liner phase FIR filter and that of linear phase log FIR filter,the authors convert linear phase log FIR filter design to linear phase FIR design.Using Remez exchange algorithm,equiripple passband and stopband characteristic of linear phase log filter can be directly obtained. |
