Concerns about digital signal processing.
¥Is it a
black box (signals in/physics out)?
¥Digital
signal processing is very flexible and the level of control can be adjusted and
matched to the skill level of the student and/or the focus of the
experiment.
¥The
analysis of the data carried out by the students can start with the digitized
waveforms or at a higher level (pulse height, integrated charge, etc.)
¥Why does it reduce
cost? A DSP, such as the PCI-5112,
costs $ 3,000, requires LabVIEW, and a Windows machine!
¥The
cost reduction associated with DSP is a result of the reduced cost of signal
processing and triggering hardware.
A wide variety of signals can be processed with the same DSP system
(although not at the same time).
