Reading a documented schematic
11 parts
The circuit is deliberately plain — two 1 kΩ/100 nF sections in a row — so that the documentation parts are the lesson. The two 'sig' net-label flags sit six cells apart with no wire between them, and the sheet works only because same-name labels are one net: rename either flag and node A and the output both read exactly 0.0000 V. The junction dot marks the one crossing that is meant to connect, where the first capacitor's return crosses the ground bus, because two wires merely passing over each other do not join. The IN and OUT port markers name the signal's entry and exit and the free text annotates the stage; all four of these are notation, with no electrical effect of their own.
