Abstract

PURPOSE:To make it possible to express a scale signal at a desired scale position with accuracy by providing a scale memory part. CONSTITUTION:Data memory part M0 of digital memory unit M is stored with the signal magnitude of each frequency analyzed by a spectrum analyzing circuit at its frequency address. Scale memory part M1 is stored with one-bit signals at respective addresses displaying a scale, and scale memory part M2 is stored with a signal at addresses of the scale discriminated especially from another scale. Those stored signals are read out to display scale marks, differing in brightness, on the screen of a Braun tube.
