A. Effective radiated power (ERP) is the mean radio frequency power multiplied by the gain of the acrial in the horizontal plane. The mean radio frequeTHEY power (RFP) will be taken as that delivered to the aerial and generally for the unmodulated condition: but in the case of systems in which the application of modulation causes an increase in the effective carrier power, apart from any change in power due to redistribution between the carrier and sidebands, this will be allowed for.
B. RFP, ERP, and the aerial characteristics will be assessed either by measure- ments or by calculation from the characteristics of the types of apparatus used, at the discretion of the Telecommunications Authority,
C. The symbols used to designate the classes of emission have the meaning
assigned to them in the Telecommunication Convention.
D. "Bandwidth" and "frequency tolerance" bave the meanings assigned to them
in the Telecommunication Convention.
