摘　　要：实时采样是最明显和最直观的采样方式,提出了两种利用多片模-数转换器(AnalogtoDigitalConverter,ADC)并行采样来实现波形实时采样的方法,借助电路仿真软件Multisim分别搭建了两种方法对应的采样电路,并通过对采样信息的后续处理观测出采样结果。结果表明,两种方法均可实现对任何波形的实时采样。Real-time sampling is the most direct sampling method in digital measurements of signal waveforms.In order to realize real-time sampling with parallel Analog-to-Digital Converters(ADC),two typical methods were brought out.Circuit design software Multisim Power Pro 14.1 was used to sketch circuits of the two methods and simulate the sampling process.The simulation indicated the effectiveness of the two real-time sampling methods.
