Amplitude FAQs:

Q: Is amplitude the change between peak and trough?

A: Yes, With appropriate circuitry, peak-to-peak amplitudes of electric oscillations can be measured by meters or by viewing the waveform on an oscilloscope.

Q: Is amplitude a displacement?

A: Yes.

Q: Is amplitude often used?

A: Yes.

Q: Is amplitude the magnitude of a pulse parameter?

A: Yes, such as the voltage level, current level, field intensity, or power level.

Q: Is amplitude usually used because it is both unambiguous and has physical significance?

A: Yes.

Q: Is amplitude simple and unambiguous only for symmetric periodic waves?

A: Yes, and like a sine wave, a square wave, or a triangular wave.

Q: Is amplitude more appropriate?

A: Yes.

Q: Is amplitude proportional to the intensity of the wave?

A: Yes.

Q: Is amplitude measured with respect to a specified reference and therefore should be modified by qualifiers?

A: Yes, such as average, instantaneous, peak, or root-mean-square.

Q: Is amplitude the maximum absolute value of the difference from that reference?

A: Yes.
