Extracted from text ... REGISTRAR PRIZE 33 Physics of invasive blood pressure monitoring sine wave and is equal to the pulse rate, thus the first harmonic. The second harmonic is a sinusoidal waveform with a frequency twice that of the fundamental harmonic. The waves are in phase, moving in the same direction and passing through zero amplitude together.5 The ideal measurement system should deal with all the harmonics of the input waveform in the same way. The amplitudes of the output harmonics will bear a constant ratio to the corresponding amplitudes of the input harmonics and there will be no phase difference between ..
