Design Introduction
The oscillograph is a common instrument that plays a key role in many experiments. Because of its
design structure, the oscillograph cannot work in some environments. For example, it may not work
when a waveform must go through projector for a demonstration or if the waveform needs to be adjusted
while the user is performing other operations.

With these issues in mind, we designed an audio-controlled digital oscillograph that uses an audio
recognition
