摘要
讨论了数字信号处理中的整形滤波在远程核四极共振里的应用．在个人计算机上用Ｔｕｒｂｏ－Ｐａｓｃａｌ编程语言实现了整形滤波，并用数值模拟谱和实验数据研究了整形滤波技术在提高测量信噪比方面所起的作用．
Application of shaping filtering in digital signal processing to the measurement of remote nuclear quadrupole resonance signals is discussed in the present article.The shaping filtering procedure is accomplished with Turbo-Pascal Language on a personal computer.Enhancement of signal-to-noise ratio by the shaping filtering is demonstrated by numerical simulations and 14N remote NQR experifmental data of a powdered NaNO2.
