Abstract : A multi-channel integrator was developed in LabVIEW to replace single function desk top integrators. A test signal consisting of 1798 points was generated in LabVIEW and read into both the software integrator and an HP-3396 Series II for comparison. Two data generation rates were employed on the data set, 100 Hz and 20 Hz, resulting in run times of approximately 18 and 90 seconds, respectively. The software integrator was tested with a raw signal input and one employing simple hardware filtering using an RC circuit. (The resistance value was approximately 820 omega, and the capacitor was approximately 2uF, providing approximately 40 - 60 Hz filtering.) The results from the software implementation of the integrator compare favorably with those recorded by the HP-3396. The software integrator has some difficulty when integrating overlapping peaks that could be overcome with a modified peak detection algorithm.
