Research on performance of audio frequency equalizer evaluation based on Support Vector Regression

A evaluate method of audio frequency equalizer performance based on Support Vector Machine was presented. Taking BPF that applied to audio frequency equalizer as experiment object. First, obtaining dataset of the amplitude frequency of the BPF by amplitude frequency characteristics testing equipment to get samples, and then using support vector regression to get the approach function of the amplifier amplitude frequency characteristics of the BPF, using the function to test four performance parameters. The experimental results show that this method improves the precision of the parameters testing. It is suitable for the evaluate of the electronic production performance that tested by oscillograph.
