Filtered Signal: Now the measurement result is wrong, because it also contains the aliased frequencies
from the input signal (the red dashed line). Note, that we don't care about the aliased signal of the blue
dashed line because this is still higher than 800 Hz.
Hint
Solution to the example described above will be described in the following chapter
“Oversampling and digital filter”.
6.1.4.2. Oversampling and digital filter
Now, let us consider the effects of oversampling. Let's assume that we oversample by a factor of N = 5.
This means that our AD converter will now sample at a speed of 2 kHz * 5 = 10 kHz and so the Nyquist
frequency is 5 kHz.
