Comparative effect of components in the bandshared spectrum of NTSC-type colour-television signals

Certain aspects of the failure of constant-luminance operation in bandshared colour-television receivers are reviewed in the light of recent developments in reproducing phosphors and the use of normalising chromaticities other than those specified for the system. Recommendations are made in order that better adherence to constant-luminance operation of colour-television receivers may be obtained under likely conditions of broadcast reception.
