METHOD AND APPARATUS FOR MEASUREMENT OF SPURIOUS VOLTAGES IN VIDEO SIGNALS

A method and apparatus for the measurement of spurious voltages in video signals by the utilization of blanking periods in which no fluctuations in time occur in the image signals other than those of the spurious signals, in which method the interference signals are so amplified that a constant spur...

Summary:A method and apparatus for the measurement of spurious voltages in video signals by the utilization of blanking periods in which no fluctuations in time occur in the image signals other than those of the spurious signals, in which method the interference signals are so amplified that a constant spurious voltage is produced, and simultaneously therewith so amplifying an indicating signal, whereby a measuring voltage proportional to the amplification results, and in which portions of video signals may be utilized which are proportional to the white value of the video signal whereby the magnitude of the resulting amplified measuring voltage is proportional to the white value and invertedly proportional to the spurious voltage.
