Abstract
Observers compared the interfering effect of multiple echoes with that of single echoes in black-and-white television pictures. The multiple echoes were 2, 4 or 8 echoes of equal strength but different delays. The single echoes were 40, 35 or 30 db weaker than the main signal. A method for estimating addition effects of several echoes is presented and demonstrated to be consistent with the test results.
