NettetThe CMSIS DSP Library contains LMS filter functions that operate on Q15, Q31, and floating-point data types. The library also contains normalized LMS filters in which the filter coefficient adaptation is indepedent of the level of the input signal. An LMS filter consists of two components as shown below. NettetWhen EEG data are collected, the EEG amplifier will at the very least have a filter that cuts off frequencies that are higher than a certain threshold. This is called the low pass filter cutoff, because the filter “passes” lower frequencies through, but attenuates (reduces) higher frequencies.
