Abstract
Three different transient audio frequencies, ranging up to 1,500 cycles per second, can be displayed simultaneously on a single beam oscilloscope. A linear sweep is applied to the cathode-ray tube and is displaced in turn to three adjustable levels, 7,500 times a second, thus effectively producing three linear sweeps. The audio inputs are sampled in sequence at the same rate so that a given audio signal appears on one trace only. Circuit diagrams and sample photographs of the cathode-ray tube presentation are included.
