The overall loudness ratio (OLR) is a term used in ITU-T Recommendation G.131 to indicate sensitivity to echo. For a complete digital connection having a one-way signal delay of 25 ms, the echo perceived by an OLR of 26 dB was detectable by 10 percent of those questioned. At a 33-dB OLR, only 1 percent noticed an echo. 25 ms is the maximum delay recommended as being acceptable without using echo suppression Advertisement: Bell Telephone download pdf Each output feeds a coupler, so the four coupler outputs supply IF signals with relative phases of 0°, 90°, and 180°, 270° which are sent to four variable attenuators driven by a microprocessor, according to the following criteria: s At every instant, two of the four attenuators insert a large attenuation into the IF signal so that its contribution to the combiner is almost zero , source: Design and testing of motion picture screens for sound picture work: A discussion of optical and acoustical considerations in the design and testing ... / Bell Telephone System.
