Set the reference
Sampling interval determines sampling frequency.
Observation records / Signal sampling
A sampled signal is a sequence of observations taken at defined intervals.
REFERENCE SESSION PLAN / NOT AN EVENT BOOKING
Prepare the assembly
Noise can arise from several independent sources.
Record a reading
A plotted trace is a representation of the samples.
Compare the sequence
Filtering changes the frequency content of a signal.
Discuss the limits
