I am doing my project in DSP 2812. I want to take in a current wave (sine wave) of amplitude 800mA inside the DSP. I understand that current should be converted to voltage. But ADC of 2812 does not accept negative values. After taking inside the sine wave (in voltage form) I need to find the total harmonic distortion. Kindly give me a solution that how to take inside the DSP a sine wave for processing.
