FAQ

Frequently Asked Questions

No, it is a very low-frequency, historical technical term.

Extremely unlikely in standard usage. It is an obsolete term. Modern devices with similar functions would be called plotters, printers, or data loggers.

Sir Charles Wheatstone, a British scientist and inventor, developed an 'omnigraph' used in telegraphy.

Its core function was to automatically convert incoming telegraphic signals (like Morse code) into written or printed characters on paper.
