Fig. 2. A linear filter can be used to compensate the effect of a linear channel h. A widely linear filter can in addition remove a real-valued noise dimension if the signal of interest is maximally improper. However, note that taking the real part is not a linear operation since ℜ(...
176 whole-brain volumes of high-resolution structural images were acquired using a T1-weighted coronal-oriented MP2RAGE sequence (TR: 5000 ms, TE: 2.98 ms; field of view: 240 × 256 × 176 mm, voxel size: 1 mm3 isotropic) using a 32-channel head coil. The pRF mapping protocol ac...

But in reality, there is no real meaning Ideal bandpass filter. The actual filter can not be completely filtered out The frequency signal outside the passband is part of the ideal passband boundary A region of frequency attenuation that cannot be completely filtered. This curve is called a ...
