In addition, in the case of television broadcast receivers, there may be radiation of power from other sources beside the local oscillator. In this standard the potential sources of spurious radiation from frequency modulation and television broadcast receivers are described and methods of measurement whereby the strength of some of these radiations may be determined are set up. Where the methods for the two classes of receivers differ, the specifications for each are outlined. 517 $a187-1951 - IEEE Standards on Radio Receivers 517 $aIEEE Std 187-1951: IEEE Standard on Radio Receivers: Open Field Method of Measurement of Spurious Radiation From Frequency Modulation and Television Broadcast Receivers 606 $aRadio frequency modulation$xReceivers and reception 615 0$aRadio frequency modulation$xReceivers and reception. 676 $a621.3841361 801 0$bNjHacI 801 1$bNjHacl 906 $aDOCUMENT 912 $a9910135516003321 996 $aIEEE Std 187-1951$92576304 997 $aUNINA
