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                
