A novel simultaneous sampling technique and its application to multipoint optical fibre sensor accelerometers (original) (raw)

2000

Abstract

Monitoring large hydroelectric rotating machines requires a multichannel system. Simultaneous sampling of several input channels is needed to avoid the propagation of initial mea- surement errors. However, this is usually not guaranteed by the acquisition hardware, due to the additional expense involved. The alternative is to correct the error caused by non-simultane ous sampling using digital signal processing tech- niques.
