Understanding Schematics: A Design Walkthrough
Every electronic design is based on a schematic diagram. The schematic diagram is the blueprint that shows how electronic components are connected to create a circuit. The schematics serve as a route map showing how current and signals will flow from the input stage to the output stage. Before a PCB (Printed Circuit Board) is actually made, we typically design a schematic. When it comes to the revision of the circuit, the main work is done first at the schematic level, and after that PCB is again modified as per specs. More than this, when it comes to circuit operation and debugging then circuit diagrams and schematic plays an important role.
