Analog divide & differentiate
7 parts
The other half of the behavioural-math family (Waveform math has the multiplier and integrator). A divider computes 10 V over a sine deliberately biased to swing 1–5 V, and a differentiator turns a 0–10 V triangle into the square wave of its slope. The one rule of analog division is designed in and worth saying out loud: the denominator must stay away from zero — the block floors |b| at 1 mV, so a zero-crossing denominator produces a huge bounded spike, not an answer. Behavioural blocks: exact mathematics on node voltages, no device physics, no offsets.
