The oversampling ratio should actually help you out, unless you have some really really close-in jammers - but even then would an analog filter help that much? The linearity of the ADC should be very good, and digitally filtering should be superior - yes? Possibly even get some bit-growth with digital filtering and decimation? Brian >
