Right. It's linear, time-invariant, but non-causal. (Hope this word exists
in English; German: "akausal")

>(PWM), but in practice there we keep the peak-to-peak voltage
>stable and let the RMS voltage drop

Notable exception: Korg PS series. Here, the pulse amplitude is changed with
pulse width. Unfortunately, it doesn't preserve the RMS value, either,
because it makes shorter pulses lower instead of higher.
