Sampling Theory

The Nyquist sampling theorem states that for a limited bandwidth (band-limited)

signal with maximum frequency f

MAX

, the equally spaced sampling frequency f

must be greater than twice the maximum frequency f

MAX

, in order to have the

signal be uniquely reconstructed without aliasing.

MAX

= f

/2 = Nyquist frequency (f

) = folding frequency

Aliasing

Aliasing occurs when signals are under-sampled (f

< 2f

MAX

). Aliasing is the signal

distortion caused by low frequencies falsely reconstructed from an insufficient

number of sample points.

Oscilloscope Bandwidth and Sample Rate

An oscilloscope's bandwidth is typically described as the lowest frequency at

which input signal sine waves are attenuated by 3 dB (-30% amplitude error).
