🔍 Key Concepts

• RC integrator behavior with different input waveforms • Relationship between time constant (RC) and the period of the input signal • How a capacitor in series with a resistor charges and discharges when driven by a square wave

💭 Think About

• Visualize what happens to the capacitor voltage during the high level of the square wave when the period is much shorter than the RC time constant—does it have time to charge very far? • Think about whether the output can follow the input quickly, or if it only responds to rapid changes (edges) of the square wave. • Compare the expected output shape for an ideal integrator given a constant input level versus very fast transitions.

✅ Before You Answer

• Confirm what an ideal integrator does to a constant (DC) input versus sudden step changes. • Check the condition "period is much less than one time constant" and how that limits the amount of voltage change across the capacitor. • Match the qualitative behavior you’ve reasoned out to the closest waveform shape among the choices (sawtooth, sine, narrow spikes, triangle).
