- Abstract:
- This paper presents a FIR adaptive filter to cancelling interference due to 50 Hz power line in human electroencephalographic (EEG) inspection. An overview of EEG techniques to study brain activity will be outlined. Then, the problem of spurious signal rejection, in this particular handset, shows the meaningfull application of adaptive filter structure. Poles of filter are driven to find an optimum bandwidth to eliminate noise. Least-Mean-Square (LMS) algorithm is used for adaptive process. Effect of finite filter length and non-zero response time, and their effect on time response will be also showed.
