Question analysis
tips: Analyze the entire question or the main part of the question content.
 
Tips: Overall design scheme block diagram column: Schematic design description
Tips: Explanation The design schematic diagram of the module in the work needs to be accompanied by a schematic diagram, preferably with a physical diagram. Each module needs to be explained. If no design is required, please indicate the source of acquisition.
