“On an oscilloscope, standard alternating current power looks like a wave with peaks and valleys occurring 60 times a second.”

“The output signals from the signal conditioner were also displayed on a digital oscilloscope for online evaluation.”

“Its receiver picked up any reflections from the ionosphere and displayed the results on an oscilloscope.”

“These observations were supported by the use of sound level and oscillograph records.”

“In Denmark in 1923, an oscillograph light modulator and selenium-cell reproducer were developed.”

“The signals that the probe receives can be displayed on a small screen with an oscillograph.”

“Sound level and oscillogram records from earlier studies were also utilized.”

“The cusk-eel oscillogram, frequency and pulse data suggested to Sprague and Loczkovich that the cusk-eel may be the chatterer source.”

“This leads to the finding of a set of regression straight lines and the establishment of an information oscillogram.”
