by waves Explanation: I think this term might do. As esmartapv had already said, the reference to communications really does indicate RF, thus 'waves' should be used. -------------------------------------------------- Note added at 16 hrs (2009-09-18 12:20:58 GMT) -------------------------------------------------- I believe your sentence should look like this: Total group delay, by waves, is defined as the group delay of a group (of components) which remain after filtering linear and parabolic components -------------------------------------------------- Note added at 16 hrs (2009-09-18 12:21:18 GMT) -------------------------------------------------- ... is defined by waves... |

Reference: ADJUSTMENT AND PERFORMANCE OF VARIABLE EQUALIZERS Reference information: MITEQ TECHNICAL NOTE 25TO14 JUNE 1995 REV B ADJUSTMENT AND PERFORMANCE OF VARIABLE EQUALIZERS (SPECIFICATION SHEET D-107) __________________________ The MITEQ Variable IF Group Delay Equalizer provides a means of compensa-tion for the non-linear delay and amplitude slope distortions that are introduced by the various components and subsystems of a satellite communications link. Group delay distortion can cause system performance degradation. These degredations are waveform distortions, intermodulation noise generation in analog FM systems, and intersymbol interference in digital systems. To compensate for these distortions, delay equalizers are used to generate a function which is opposite to that of the delay response of the unequalized system. Due to the nature of these distortions, it is necessary to have the capability of user adjustment. The MITEQ Variable IF Group Delay Equalizer is designed to allow all system group delay distortions to be eliminated by inserting compensation at IF frequencies (70 MHz or 140 MHz). A properly compensated group delay response will yield a constant propagation delay over frequency thereby Reference: http://www.miteq.com/satcom/tns/MITEQ%20Tech%20Note%2025T014... |
