Efficient CPS Method for Improving the Sampling Resolution of Periodic Signals

Article Preview

Abstract:

Based on existing analog to digital converters (ADC), this study proposes a simple and reliable controlled phase shift (CPS) method to improve the sampling resolution of a periodic signal. The proposed method uses phase shifted sampling sets of a sequence of sampled periods to increase sample resolution. When combining these sets, the period is virtually sampled with a higher number of samples. The lower sampling rate (per period) alleviates the requirements to be imposed on the conversion time of the ADC. Under the original conversion time of ADC, the proposed method can provide more sampled signals. Experimental result shows the proposed CPS method can improve the sampling resolution of periodic signals.
