1) Valid-bit

有效位

2) Effective potential

有效位势

3) effective number of bits

有效位数

4) effective bits

有效位数

The Measurement of Respondence Characteristics and Effective Bits of Digital Storage Oscilloscope;

数字存储示波器响应特性及有效位数的测量

In most effective bits evaluation of waveform recorders, the prerequisite is that there is no signal source distortion, or the distortion can be neglected.

波形记录仪和数据采集系统等设备的动态有效位数评价中,大都假定所用正弦波信号源无任何失真。

5) ENOB

有效位数

Results from both theoretical analysis and experimental simulation show that the proposed S/H circuit has a sampling rate of 60 MHz with ENOB at 7.

0 MHz输入信号频率范围内,其有效位数达到7。

The result of performance test shows that the inter-channel consistency of dual-channel sampling circuit is perfect and the ENOB of ADC is more than 6 bits, which satisfies the application requirement.

对系统进行的性能测试表明,I、Q双通道采集到的信号相位一致性能较好,A/D有效位数为6位以上,满足实际应用的需要,适用于高速数字信号处理领域。

In data acquisition,a sine wave is input to system,and DSP is used to control sampling,and analog-to-digital converted data is stored and FFT transformed,so the Signal-to-Noise Ratio(SNR) and effective number of bits(ENOB) of the ADC can be analyzed.

在采集过程中采用纯正弦信号作为输入信号,用数字信号处理器(DSP)控制采样,并将A/D转换后的数据存储,进行FFT变换,进而来分析ADC的信噪比及有效位数。

6) significant figure

有效位数

New comprehension for significant digits is brought up in :any measured value is significant digits which include accurate value and uncertain value and which are decided by significant figure.

指出现行大学物理实验教材中有效数字的概念存在不足之处,提出在大学物理实验教学中有效数字的新解释:任何测量值都是有效数字,所有的有效数字都包含有准确值和存疑值,有效数字的位数由有效位数来确定。

The paper discusses the basic method of determination of significant figure of measure result on the basis of analyzing various error.

阐述在分析各种误差的基础上如何确定测量结果的有效位数的基本方法。

补充资料：有效位数

对没有小数位且以若干个零结尾的数值,从非零数字最左一位向右数得到的位数减去无效零的个数;对其他十进位的数,从非零数字最左一位向右数而得到的位数就是有效位数.
