摘要

This paper presents some results of a measurement campaign in the service area of the digital terrestrial television (COFDM-8K system) experimental network of Madrid (Spain). The purpose of this survey has been to determine the degradation suffered by analogue PAL-G signals in the presence of co-channel and adjacent channel digital emissions. The result is a curve that estimates the protection ratios between analogue and digital received power levels
