Design of third-octave band FIR digital filters based on MATLAB

CHENG Feng 1, ZHOU Bao-kun 1, CHENG Li-qing 2, HUANG Jing-dang 1, WENG Hong-lin 1 (1. College of Mechanical and Electrical Engineering, Fujian Agriculture and Forestry University, Fuzhou, Fujian 350002, China; 2. College of Information Science and Technology, Fuzhou University, Fuzhou, Fujian 350002, China)  
After deeply analyzing the stipulation for third-octave band filters in GB/T 3241-1998, this paper presented a mathematical model which matched the parameters' interface of functions used to design FIR digital filter in the MATLAB signal processing box, and third-octave band filters were designed through programming. The evaluation showed that the designed result met the requirements of type 1 precision.
