Abstract

A process for analysing an analogue/digital terrestrial and/or digital cable television signal, especially suitable for being used by operators and technicians for performing automatic signal type recognition, comprising the following steps: selecting a television channel within the specific band of the country wherein operations are carried out; measuring the signal at the frequency of the analogue video carrier within the selected frequency band; performing at least one measurement of the signal at the band centre frequency of the digital channel within the selected frequency band; - performing one or more verification tests on the signal values within the selected frequency band, suitable for determining whether the television signal is an analogue signal, a digital terrestrial signal, a digital cable signal or a not defined signal.
