Attention: Make sure the sum of your inputs does not exceed the machine unit (±10V), otherwise an overload will occur
I don't think this is correct. An overload occurs when the output exceeds the machine unit. However it should be no problem if the sum of the inputs exceeds the machine unit. — Preceding unsigned comment added by MKoch (talk • contribs)
- Well, if the sum of the inputs exceeds the machine unit, the output will also do so, isn't it? You could think of cancellation of overloads (like in a sum with three inputs, two in overload but opposite sign, like
+15V-15V+5V = +5V). This is a border case similar to saying+infinity - infinity + 5 = 5, because actually an overload value is typically an illegal value on the computer and the upcoming computation is most likely wrong. --Sven (talk) 13:51, 1 October 2021 (CEST)- No, if the sum if the inputs exceeds the machine unit, that doesn't mean the integrator's output will exceed the machine unit.

- When you connect a -1 signal to the input then the output will ramp from 0 to 1 in 1ms. Overload after 1ms. When you connect two -1 signals to two inputs of the same integrator, then the output will ramp from 0 to 1 in half the time. Overload after 0.5ms.--MKoch (talk) 14:15, 1 October 2021 (CEST)
