WERKWIJZE EN INRICHTING VOOR HET METEN VAN DE ONTVANGKWALITEIT VAN EEN IN FREQUENTIE GEMODU- LEERD ULTRAKORTE-GOLFSIGNAAL.

摘要

There is proposed a simple possibility of assessing the quality of the VHF stereophonic reception in an oscillogram. The amplitude of the VHF signal carrier is adjusted to a constant value and simultaneously the interfering amplitude modulated upon the VHF signal carrier is left unaffected. By this means, the reference axis formed by the carrier amplitude is retained in the oscillogram during the entire measuring operation.
