Optical Imaging and Tissue Characterization with Polarization Discrimination of Time-Gated Signals
      


"QRS" complex of the "ECG" can be extracted from various noise interference background as follow: the input electrocardiogram, signals are divided into two channels, which are treated by filters. Then, these two signals are used as the input and gate signal of zero level restoring gate respectively.

将输入的心电信号分成两路,经适当的沪波处理后,分别作零电平恢复门的输入和门控信号、便可从各种噪声干扰中将“QRS”波群分离提取。

The present paper proposes a simple scheme, which involves synchronous gated circuit with the radio-frequency pulses, to construct probe that exhibits different Q values between the transmitting and receiving periods. This proposal results in a dramatic reduction of the recovery time of the probe without attenuating the S/N of 14N NQR spectra. The experimental result demonstrates that with suitably chosen R, the damping resistor, the "dead-time" of the spectrometer can be confined in 20μs by using the suggested...

The present paper proposes a simple scheme, which involves synchronous gated circuit with the radio-frequency pulses, to construct probe that exhibits different Q values between the transmitting and receiving periods. This proposal results in a dramatic reduction of the recovery time of the probe without attenuating the S/N of 14N NQR spectra. The experimental result demonstrates that with suitably chosen R, the damping resistor, the "dead-time" of the spectrometer can be confined in 20μs by using the suggested probe circuit.

利用一与射频脉冲同步的门控信号使探头在发射和接收时呈现不同的Q值.从而能够在不降低接收14NNQR信号的情噪比条件下极大地缩小探头的恢复时间.初步的实验结果表明:通过适当选择衰减电阻的阻值,提出的探头设计能够将常规探头的'死时间"限制在20μs以内.

A pulse counting with gate controlling,if the relation of gate signal and counting signal is random,the quantized taking values and quantized errors follow a bi point distribution,while the arithmetic means of repeated measurement follow a binomial distribution;if their relation is steady,then the quantized taking value and quantized error are both steadily single values.According to these results,the uncertainty calculation,in some measurements like that frequency,should be to include the standard error...

A pulse counting with gate controlling,if the relation of gate signal and counting signal is random,the quantized taking values and quantized errors follow a bi point distribution,while the arithmetic means of repeated measurement follow a binomial distribution;if their relation is steady,then the quantized taking value and quantized error are both steadily single values.According to these results,the uncertainty calculation,in some measurements like that frequency,should be to include the standard error calculated from bi point distribution in single measurement but the standard error calculated from binomial distribution in repeated measurement;in some measurements like that voltage,should be to include ±1 error of one digit of the end of display value.Based on the supposed distribution of each error quantity,the combined standard uncertainty or expanded uncertainty can be figured out.

对于门控脉冲计数,若门控信号与计数信号间的关系是随机的,则量化取值和量化误差遵循二点分布,多次测量的算术平均值遵循二项分布;若门控信号与计数信号间关系是固定的,则量化取值和量化误差为稳定的单一值。根据这些规律性结果,频率等测量的不确定度计算,单次测量应计入按二点分布计得的标准差,多次测量应计入按二项分布计得的标准差;电压等测量的不确定度计算,应包括相应显示值最后一位的±1个字的量化误差。在对各误差分量作出较切合实际的分布假定基础上,求出合成的标准不确定度或扩展不确定度。
