    Karteek,

    The accuracy of the metrology data reads that is demonstrated by this reference design is fairly high. Although the CC3200's ADC is 10ENOB, the accuracy is improved by oversampling and decimating the samples through block summing, yielding a 13-bit ADC with 0.98-K samples per second. This ADC Metrology software module can achieve as low as 2% measurement accuracy.

    More information about the digital signal processing algorithm can be read from Section 3.2.3 of the TIDC-CC3200SMARTPLUG User's Guide.

    BR,
