Digital Signal Processing, English: Digital Signal Processing, abbreviated as DSP, is a professional basic course for electronic information disciplines. Its basic concepts and basic analysis methods have penetrated into information and communication engineering, circuits and systems, and integrated circuit engineering. Biomedical engineering, physical electronics, navigation, guidance and control, electromagnetic field and microwave technology, hydroacoustic engineering, electrical engineering, power engineering, aeronautical engineering, environmental engineering and other fields.

Digital signal processing problems are ubiquitous, and information science has penetrated into all modern natural and social science fields. We should be proficient in basic theories and basic analysis methods, and use these classic theories to analyze, explain and calculate signals, systems and their mutual constraints.

How to import third-party libraries in ThinkPHPHow to import third-party libraries in ThinkPHP

03Jun2023

Third-party class libraries Third-party class libraries refer to other class libraries besides the ThinkPHP framework and application project class libraries. They are generally provided by third-party systems or products, such as class libraries of Smarty, Zend and other systems. For the class libraries imported earlier using automatic loading or the import method, the ThinkPHP convention is to use .class.php as the suffix. Non-such suffixes need to be controlled through the import parameters. But for the third type of library, since there is no such agreement, its suffix can only be considered to be php. In order to easily introduce class libraries from other frameworks and systems, ThinkPHP specifically provides the function of importing third-party class libraries. Third-party class libraries are uniformly placed in the ThinkPHP system directory/
