Annex A (informative) Bibliography
Deals with methods of measurement for transmitters including modulators, and receivers including demodulators, used in digital radio-relay systems. Measurements for adaptive equalizers are given in IEC 60835-2-8. This consolidated version consists of the first edition (1993) and its amendment 1 (1997). Therefore, no need to order amendment in addition to this publication.
