Abstract
The technical advantages of measuring complex impulse responses rather than the in-phase component of broadcast teletext channels and the extraction of channel information from real impulse response measurements and its limitations are described. A number of illustrative examples are provided. It is concluded, after discussion, that measurements of channel complex impulse responses are necessary, in spite of the extra cost, so that suitably flexible and general computer simulation design and performance studies of broadcast teletext systems can be made.
