A review of equalisation techniques for analogue television signals

摘要

Automatic equalizers are considered, in relation to their suitability for inclusion in the existing national television networknBoth time-domain and frequency-domain equalizers are discussed and it is concluded that, whilst the great majority of links should continue to be equalized individually using fixed, passive equalizers, improved average overall performance would most probably result if automatic frequency-domain equalizers were added at suitable points in the network in order to correct both the residual distortions of the links and their variations with time.
