4. How to observe waveform of voice sound: Input your cardinal vowel such as [ɑ] (Fig.8) and [u] (Fig.9) into the microphone, then, you will see the waveform displayed. Fig.8 Sound waveform [ɑ] Fig.9 Sound waveform [u] Observation of the waveform of non-audio electric signal from an oscillator Plug the probe in the BNC input connector at the top of the Oscilloscope (Fig.10), pinch the probe to an output terminal of the oscillator with the probe tip (Fig.11). - Page 9 AC/DC/GND Selection switch on the top panel might not be set to “AC”. (Set the switch to “AC”.) and/or d) input voice might be too weak. (Input loud voice into the microphone.) www.global.narika.jp...
