Defination of "TCG"
Time-dependent gain (TDG)
Time dependent or swept gain function fitted to some ultrasonic instruments to
correct for the distance related reduction in reflected amplitude.
Editor comment: Usually called DAC 'distance amplitude correction' or TCG 'time controlled gain'
This definitions is used in the standard EN 12688-1 "Characterization and verification of ultrasonic examination -
Part 1: Instruments" For other definations the EN 1330 shall apply.
