Abstract
A variable bandwidth filter (VBF) is proposed for cleaning bio-medical signals with known boundaries in time-frequency domain (TFD). Also, the behaviors and the characteristics of the VBF are examined in TFD. The proposed VBF clips a noisy signal along the boundaries of the known instantaneous boundary (IB) and rejects noise in the outside of the IB of the signal in TFD.
