Define
Sampling interval determines sampling frequency.
Signal sampling
A sampled signal is a sequence of observations taken at defined intervals.
Prepare
Noise can arise from several independent sources.
Observe
A plotted trace is a representation of the samples.
Review
Filtering changes the frequency content of a signal.
