Audio-range ladder

Two series resistors and two shunt capacitors form distinct interstage/output nodes with a shared return. 4.7 kΩ and 10 kΩ series legs with 22 nF and 10 nF shunts expose the loaded interstage node.

Expected vs. actual

An inspectable result.

These checks compare the renderer outcome with the declared case expectation. The stress test also checks determinism, geometry, and connectivity.

Electrical nodes & connectivity

Each net is one electrical node: the named endpoints below are connected. Component pins and external ports are endpoints. These counts are not the number of geometric junction dots or wire bends. No voltages, currents, or simulation results are inferred.

Components: 4
Electrical nodes / nets: 4
Component pins: 8
External ports: 3
Connected endpoints: 11
