Channels hum in parallel thought: one bright, one dim, another asleep. Knobs hold conversations—gain, time-base— fingers learn the dialect of resistance. A probe's tip kisses a circuit's skin; sparks of syntax translate current to arc.

: Digital models use an analog-to-digital converter (ADC) [17]. A higher sample rate (e.g., 1 GSa/s) ensures fast-changing signals are captured without losing detail [1, 15]. Triggering
