基于MATLAB电路特性演示平台的设计
摘要
电路特性是用复杂的数学公式描述的,非常抽象,难以理解。MATLAB具有强大数学计算和图形显示功能,它可以方便的计算出非常抽象、复杂的数学公式。此外,它提供了图形用户界面设计工具GUIDE,其包含的各种控件,易于开发,交互性强、使用方便。
本论文基于MATLAB GUI开发设计的电路特性演示平台。平台共包含有8个常见的、典型电路的特性演示和方波傅里叶分析。各演示平台的开发是在已建立的数学模型的基础进行的,利用MATLAB中的GUIDE设计工具完成了用户界面的设计,界面中各种控件的功能是通过编写其回调函数来实现的。
在演示过程中,通过调整相关的参数,动态演示电路参数变化时电路特性的变化情况。该系统平台具有良好的用户界面、交互性强、操作方便,可以使用户直观、高效地观察和理解电路的特性。

The Design of the Circuit characteristics of MATLAB-based presentation platform
ABSTRACT
Circuit performance is to plex mathematical formulas described, very abstract and difficult to understand. MATLAB has a powerful mathematical and graphical display, it can easily calculate the very abstract plex mathematical formula. In addition, it provides a graphical user interface design tool GUIDE, which contains the various controls, easy-to-development, interactive, easy to use.
This paper, based on MATLAB GUI development and design of the circuit features demo platform. Platform contains a total of mon, the characteristics of a typical circuit, and square wave Fourier analysis shows. The demonstration platform was developed to build on the basis of mathematical models, the use of MATLAB in the GUIDE user interface design tools plete the design of the interface functions of the various controls is through the preparation of the callback function to achieve.
In the demo, by adjusting the related parameters, dynamic parameters demonstrates the circuit characteristics of circuit changes. The platform has a good user interface, interactive, easy to operate and allows users to directly and efficiently observe and understand the characteristics of the circuit.
