适用范围
The CCIR, CONSIDERING (a)that frequency assignment plans must of necessity take into account the characteristics of receivers ; (b)that the range of performance of receivers used by the public is very large; (c)that a reference receiver with characteristics based on currently available receivers may be useful in a planning context; (d)that standards for reference receivers should therefore be defined, which can be taken as a basis for frequency planning purposes; (e)that these standards need to be taken into account by receiver manufacturers, UNANIMOUSLY RECOMMENDS that the receiver characteristics contained in Annex I should be used for AM sound broadcasting planning purposes.
