Which of the following is an advantage of an oscilloscope versus a digital voltmeter?
An oscilloscope uses less power
Complex impedances can be easily measured
Greater precision
Complex waveforms can be measured✓پاسخ درست
توضیح
A digital voltmeter reduces a signal to a single number, usually an average or RMS value, whereas a waveform display plots instantaneous voltage against time so the shape of a complex signal can be seen and measured. Showing that time-varying detail is the advantage.
