A classic petrol injector waveform features a drop to 0V (grounded by ECU), a steady on-time, and a massive inductive voltage spike (often 60V–100V) when the circuit opens. A small dimple in that upward inductive spike reveals the actual physical movement of the injector pintle closing. Communication Networks

: Technicians compare captured waveforms against "known good" reference signatures to spot anomalies in electronic systems. Common Waveforms & Test Procedures pdf automotive oscilloscopes waveform analysis

AC signals periodically reverse direction, generating sinus waves that alternate above and below a zero-volt reference line. A classic petrol injector waveform features a drop
