narrowbandpass filter
- Thread starter bunnu
- Start date
100 Hz bandwidth at 28 kHz indicates a Q of 280. This is achievable, but is not enough of a specification to allow anyone to design a filter. You must know what the separation is between the passband and the stopband, what the minimum attenuation in the stopband must be, and how much ripple is allowed in the passband. And you also need to know if the filter design is passive, active, analog, digital, and then a number of other circuit questions must be addressed before detailed design commences.
