摘要： A display circuit of an oscillscope to switchingly display waveforms and characters has substantially no fluctuation phenomena caused by switching waveforms and characters. Each driving amplifier for waveforms and characters is employed to drive a final stage amplifier of which outputs are applied to deflection plates of a CRT. As a driving amplifier is not used in common to amplify waveforms and characters, clear waveforms and characters are observable without fluctuations.
