Specifically, the filter needs to …
WebA simple RC filter after the switched capacitor filter creates a very good sine wave with very low distortion. As you can see, it is a very nice sine wave. Photo 6 demonstrates this with the harmonics lost in the noise floor that is over 60 dB below the fundamental. This sine wave has less than 0.1% distortion.
