摘　　要：正弦曲线在日常教学中应用广泛,但目前教仪中没有一种能快速而精确绘制正弦曲线的绘图教具。一般课程教学中常采用徒手绘制的方式,所得到的图形既不精准又不美观。针对这一现象,设计一种能绘制不同振幅、周期及初相角的正弦曲线绘图仪,可应用于信号处理中的模拟信号、物理的简谐运动、交流电的电压改变等正弦曲线的研究和教学使用中。通过分析并验证该装置具有结构简单紧凑、操作灵活方便等特点,可有效满足课堂教学和学生学习质量要求。Sine curve is widely used in daily teaching,but at present,there is not a kind of drawing aid which can draw sine curve quickly and accurately.The method of freehand drawing is often used in general course teaching,and the graphics obtained are neither accurate nor beautiful.In view of this phenomenon,a sinusoidal plotter which can draw different amplitudes,periods and initial phase angles is designed.It can be used in the research and teaching of sinusoidal curves in signal processing,such as analog signal,simple harmonic motion of physics,voltage change of alternating current and so on.Through analysis and verification,it is proved that the device has the characteristics of simple and compact structure,flexible and convenient operation,and can effectively meet the quality of classroom teaching and students'learning.
