Abstract
A television receiver includes a video display for producing a video display image in accordance with a received television signal and a power supply responsive to an irregular current drain for perturbating the video display image. A telephone interface circuit coupled to the power supply is responsive to a viewer initiated dialing signal for completing a telephone connection with the corresponding telephone number in a manner so as to cause an irregular current drain from the power supply. The resulting perturbations otherwise present in the video display image are eliminated by a circuit cooperating with the telephone interface circuit for effecting a substantially uniform current drain from the power supply in response to the dialing signal.
