Abstract
The paper proposes a new method for Word Error Rate (WER) measurement for digitizing waveform recorders. In particular, a WER estimation procedure, based on Student's t distribution, is provided to estimate the WER and its confidence interval, minimizing the acquisition record length. The proposed test procedure has been experimentally verified by means of WER measurements on actual digitizing waveform recorders, where the test results have been compared to those achieved by implementing the method described in the IEEE Std.1057. Two measurement set-ups have been adopted in order to prove the validity of the proposed approach.
