For a band-pass filter, you can calculate its Q factor as f0/BW. For a low-pass filter, its f0 is same as BW, right? But I find some low-pass filter's Q value is 0.5 or 1.5, How it can be?

i mean frequency above Fo in LPF (and below Fo in HPF) you will find
efect of Q factor in frequency responce.
