Abstract :
By using directly comparison method, the fundamental of DAC stepwise signal can be used as calculable AC voltage reference. A directly fundamental comparison system based on a normal commercial DAC is constructed to demonstrate the practicability of this method. The effects of the DAC quantization and the transients between adjacent steps affecting its fundamental wave are also studied.
