Description: This works with MSP430 microcontroller as the core, based on DDS principle, by look-up table output step sizes for the 10HZ, frequency of 100HZ ~ 2KHZ sine wave. Two by the signal zero-crossing comparator, XOR, rectification and low-pass filtering, the realization of the phase of the measurement error is less than
