Artifacts in First and Second Sounds of the Phonocardiogram [PDF]
Circulation, 1974 Phonocardiographic instrumentation tests using a square wave of sound pressure reveal differentiation spikes at the output of a dynamic microphone and at the amplifier-filter during initial onset of the test pulse. When the pulse reaches the plateau level, ringing oscillations can be observed in the amplifier-filter combination.
