Hy guys,
I have to design an anti-aliasing filter for a 16-bit ADC with a sampling frequency of 200 kHz with the following specification:
- Pass Band Gain H=10dB with +/- 1 dB ripple
- Off Band Gain Hoff=-40dB
My understanding is that the staff frequency (the one at -40dB) should be 200kHz/2 for Nyquist. However, it seems that there are no information about the cut-off frequency of the filter which is fundamental parameter for the design. Is it possible to derive it considering that we have 16-bit ADC or it is a missing input?
Thanks!
