R&D Report 1975-24 : Prototype equipment to measure co-channel interference on 625-line television signals. M.J. Kallaway This report describes prototype equipment designed to measure the level of co-channel interference (CCI) on a 625-line television signal. The CCI measuring equipment's primary application is at transmitters fed by re-broadcast links (RBL) where it would measure the level of CCI on the incoming television signal and record it on a chart recorder. The CCI measuring...

R&D Report 1982-15 : L.F./M.F. radio-data: compatibility tests. A.G. Lyner This report describes investigations which have been carried out to establish suitable parameters for an angle-modulation system for adding data signals to an m.f. or l.f. sound broadcast programme. Mechanisms causing crosstalk between data and sound channels in such a system are discussed and the likely degree of crosstalk is assessed. Suitable parameters for a data-signalling system are suggested, based upon...
