Abstract
A method of using a standard cathode-ray oscillograph to present low-frequency or direct-current conditions is described. In the interest of sound on-film recording the paper describes how an electronic switch is used to generate repetitive pulses of audio signals as a second electronic switch is used to pick up the signals and the resulting noise-reduction-bias envelope and place them in reference positions on the oscillograph.
