This page allows the user to calculate the coherent frequencies values involved of the
acquisition process. It gives an indication where the 6 first harmonics are located in
the Nyquist zone.
Enter your analog and sampling frequencies in field
.
Indicate the number of
samples to be acquired
, as well as the fixed parameter for the coherency
calculation (Fs in our example above
). Press “UPDATE GRAPH” to look at the
frequency plan, it gives also the real Fin frequency (Refer to
details on coherency calculation):

Note: The level of the harmonics shown does not reproduce the behavior of the ADC;
they are only given as indication for location.
