Abstract
A method for correcting data conversion/transfer errors in each of a plurality N of channels of a vibratory energy imaging system, by: providing an addressable memory having a plurality L=2.sup.M locations, each for storage of a data word of B bits; then storing in each of the L locations of the memory means a B-bit data word having a value selected to cause the output-to-input transfer function for that channel to assume a desired relationship, with respect to a standard transfer measure; and selecting that one of the L data word locations, responsive to that actual one of an M-bit data word output from a channel ADC or from a data bus, responsive to a test signal, in which to place corresponding data.
