Basic outline and idea of where voltage and current will flow through; the "blueprint" of our design.
Once the right components and layout has been established, the next phase involves intentional placement and connections between the components.
The final board display the components combined with a simulated board including solder masks (green-colored layer) and a copper plate.
Consists of three sections.
Virtual ground
Amplifier stage
Filter stage
High-pass
Notch
Low-pass
