A plating apparatus and method for deposition of a conductive material on a semiconductor wafer having surface portions and cavity portions. At least two field effect transistor channels, each having a drain and source are connected to corresponding ones of the at least two input fingers. Thus the user can verify how the transformed image will look before it is printed. The predicted output value may be, for example, an average of the previously transmitted output values or a previously transmitted output value that was transmitted in response to a previously received input value that is similar to a currently received input value. A coil-specific pixel magnitude and a coil-specific pixel phase are respectively determined from a coil-specific MR data set of one of the multiple coils.
