Circuit Diagram symbol

From: http://www.360doc.com/content/10/0419/12/952018_23781379.shtml

 

Circuit Diagram symbols are represented by a painting or calligraphy image.
The symbols of electronic components (such as capacitors, resistors, diodes, three-pole functions, and integrated circuits). With the circuit diagram symbols, I can learn, demonstrate, and design them easily on the drawing.
