Abstract

When measuring delay profile in digital terrestrial television broadcasting, errors of delay wave level occur when the delay time is not an integer of the sampling interval. Therefore, we created theoretical formulae expressing these errors and developed an apparatus with higher level accuracy with the compensation method.
