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.
