<p>A data collector (40) having a digital signal processing circuit (46) that receives a digitized vibration signal (59), and performs processing steps to isolate high frequency pulses (18) in the digitized vibration signal and quantify energy content of those pulses by detecting a peak negative value of the digitized peak-to-peak amplitude of the received vibration signal, and then using this peak negative value to compute a maximum peak-to-peak value of the received vibration signal. The resulting maximum peak-to-peak value comprises a peak-detected digital output signal that may be stored and/or displayed to a user as a reflection of the high frequency content of the vibration signal, or frequency transformed for storage and/or display to a user.</p> |
