The present invention aims to enable the accurate learning of a true torque point in a wet friction clutch, prevent the clutch connection shock by absorbing the response delay upon an ordinary clutch connection control, and to successfully combine the time lag and shock. An equalization circuit in a receiver may include a decision feedback equalizer circuit having a first plurality of tap coefficients that are determined based on a cost function that receives as input an error signal that is an inter-symbol-correlated signal. The device also includes a graft secured to the stent and made of a suitable biocompatible material. A shoulder portion 14A is produced following the seed crystal, and a planar body 14B is produced following the shoulder portion. Filtering via the second filter may be based on the current pixel and a collocated pixel of the previous second blended video image or of the previous filtered output video image.
