Design of Visual Communication Digital System Based on CAD

Communication is the transmission of information through a certain medium, with the purpose of transmitting information. Communication systems are the generic term for technical systems used to complete the information transmission process, and their role is to send information from a source to one or more destinations. Modulation and demodulation occupy an important position and are indispensable in the process of information transmission, so it is extremely important to study the modulation and demodulation process of a system. The traditional visual communication automation digital system has the problems of poor visual communication effect and low efficiency of visual information transmission, so it can only design a single element and lacks visual order. In order to solve the above problems, a visual communication automation digital system based on CAD is designed, and the hardware and software are designed. The design of visual communication digital system based on CAD is a process involving the creation and development of various graphics and images, icons, logos, symbols and other designs. It also includes the use of computer aided drafting (CAD) software to create these designs from drawings or sketches. The main purpose of creating this type of digital system is to develop an effective way to transmit information in an effective way, with the least errors in spelling and grammar. This is because it can be used as a tool to effectively exchange ideas between different people involved in different projects or activities related to visual communication.
