The subjective effect of intermodulation distortion when sound and vision signals are amplified in a common amplifier

摘要

This report examines the relationship between the subjective and objective effects of intermodulation impairments introduced into 625-line System I television systems, when sound and vision signals are amplified in a common amplifier. The variation of impairment with sound modulation is discussed. No account is taken of the distortion of the sound channel or cross modulation.
