Title:
WAVEFORM DISPLAY METHOD
Document Type and Number:
Japanese Patent JP2678872
Kind Code:
B2
Abstract:
PURPOSE: To realize the waveform display method which keeps the resolution of a waveform which is displayed at some extent and provide favorite display mode even when the waveform stored in a memory is magnified or reduced displayed.
CONSTITUTION: A CPU 2 reads waveform data representing the waveform out of the PCM waveform memory 7. When the waveform is enlarged and displayed on a display device 10, the CPU 2 interpolates the read waveform data to generate interpolated data, and enlarges and displays the waveform. When the waveform is reduced and displayed, the CPU 2 reduced-displays the waveform by thinning out the read waveform data.
