The performance requirements of a television monitor receiver (nyquist demodulator) and methods of measurement

A high-quality monitor receiver is normally used at television transmitter stations for measuring and monitoring purposes. The performance of this receiver is discussed on the basis of the ideal characteristics, as specified by C.C.I.R., and the characteristics which lie within practical tolerance limits. The problem of testing the receiver is considered, and selected measuring procedures, which have been used in an extensive test service for the Norwegian Telecommunication Administration, are described.
