针对数字滤波器内容抽象、理论性强、不易掌握等问题，开发了基于LabVIEW的数字滤波器示教软件。对该软件的编程方法进行详细阐述，并利用其对含噪语音进行了处理，对处理结果进行了分析。实践表明，利用LabVIEW编写数字信号处理示教软件具有简单明了、易于上手的特点，将其应用于教学中可明显增强学生的学习兴趣、明确学习目的、提高感性认识、强化理论学习效果，对培养学员的实践意识和实践能力具有重要意义。

The digital filter is abstract, theoretical, and it is difficult to be understood, so the digital filter teaching software is de-veloped using LabVIEW. The programming method is introduced in detail. The software is used to deal with a section of speech with noise, and the results are analyzed. The practice indicates that it is easy to develop a teaching software using LabVIEW, which can stimulate students’interest in learning, clear learning goal, improve the perceptual knowledge and strengthen the theoretical study. It is of great significance to train the students’practice consciousness and ability.
