Embodiment Construction
[0029] In order to make the purpose, technical solution and advantages of the present invention clearer, the implementation manners of the present invention will be further described in detail below.
[0030] Therefore, in order to solve the above problem of frequency band feature extraction and its flexible configuration of frequency band parameters and reduce the amount of calculation, the present invention proposes a filter bank structure and its configuration method with rapidly configurable frequency response characteristics, based on which the device is given Implementation. For details on the all-phase filter design method, refer to literature [13,14], but literature [13,14] does not involve the problem of filter banks, nor does it involve the problem of fast configuration coefficients of filters. Based on the literature [13,14], the filter bank designed by the present invention can flexibly divide the position of each frequency band of the signal, and accurately measur...
