(OP)
What minimum stopband attenuation is required for the reconstruction filter after DAC? I am designing guitar reverberator and echo with 8 bit ADC & DAC

RE: Active filters

Hi, you can set the filter to just as much as you need for your signal. You will need more than 8 bits if you want it to sound ok 12bits would be a minimum.
