Formulae (4)

f_s \geq 2f_{max}

Minimum sampling rate to capture a signal without aliasing.

f_s \geq 2 f_{max}

To digitise an analogue avionics signal without aliasing, the sampling rate must be at least twice the highest frequency present.

f_s \ge 2 f_{max}

Sample at least twice the highest frequency to avoid aliasing.

f_a = |f - n f_s|

Frequency an under-sampled tone masquerades as.
