Forum Post: DC filter application in sigma delta ADC in MSP430F67791A

Hi, I have downloaded some metrology code for my project (Energy meter project). Part of code contains a DC filter. So, i want to know what would be side effects if i remove DC filter Code: if ((V_sample >= V_ADC_MAX || V_sample metrology.V_endstops) phase->metrology.V_endstops--; V_sample = dc_filter_voltage(phase->metrology.V_dc_estimate[normal_limp], V_sample);
