MATLAB: How can i filter a EEG signal

eeg signal processingfir

I'm working on EEG data with noise, Now, I have to design a FIR filter to extract EEG data. Could anyone help me please

See for example: hi all, i'm having trouble to get transfer function for these sub-band frequency (link). These are IIR filters, however you can easily use this information with fir1 (link) or kaiserord (link) to design a FIR filter. The designfilt (link) function is also an option.

As the frequency response of the Butterworth filter is maximally flat (no ripples), you do not have an option to specify the passband ripple and stopband attenuation values in butter function. In designfilt, you can specify the passband ripple and stopband attenuation values, however, they are not accepted for butterworth filter. You can use designfilt to design a butterworth bandpass filter as shown below.

d = designfilt('bandpassiir', 'FilterOrder', 20, 'HalfPowerFrequency1', 0.4, 'HalfPowerFrequency2', 0.6, 'DesignMethod', 'butter');
