【Abstract】 Abstract This paper discusses the difference between signal reconstruction and parameter measurements. Then, it studies sampling condition in sampling measurements of periodic repetitive signals. Finally, it analyzes the error caused by aliasing, and several measures are proposed to reduce the error.更多还原
