TECHNICAL REFERENCE MANUAL
Analog filter, oversampling and digital filter
You can see that the analog filter does not have a very sharp damping but this is not required. The
important thing is, that the attenuation of the analog low-pass filter increases for higher frequencies.
Analog filtered: The troublesome part of the input signal (red dashed line) is already highly damped
before we even sample it! Also some other parts of the input signal are damped but those parts are
way higher than the frequency range that we are interested in f
f
: so this is also not a problem.
Sampled Signal: the sampled signal shows the same folding effect as before, but this time the aliased
frequencies have only very little amplitude (because of the analog filter).
