Transient Voltage Analysis
I’m using C1 to filter some of the noise of a flickering light. That light flickers +/- 10% from the mid point of the resistor every 10ms. Use the @simulator to show me the transient voltage across the LDR

Here’s the summary of the transient voltage at net2 (across the LDR):
Table
| Parameter | Value |
|---|---|
| DC Level | 2.50 V |
| Ripple Amplitude (±) | 32 mV |
| Flicker Frequency | 100 Hz |
The RC filter (R1 = 10 kΩ, C1 = 1 µF) reduces the ±10% flicker on the LDR to approximately ±32 mV around 2.50 V. No further simulations are required.

Can you give me a plot on how the voltage across the LDR would be with and without C1 using the @simulator ?

Here’s a comparison of V(net2) over 20 ms:
Table
| Condition | Min Voltage | Max Voltage | Peak-to-Peak | Ripple Frequency |
|---|---|---|---|---|
| With C1 (RC Filter) | 2.456 V | 2.532 V | 0.076 V | 100 Hz |
| Without C1 | 2.370 V | 2.630 V | 0.260 V | 100 Hz |
The RC filter reduces the ±10% flicker from ±0.13 V to ±0.038 V around the 2.5 V midpoint.

I’ve run both transient simulations. Here’s a combined plot comparing the voltage at NODE (across the LDR) over 20 ms:

- Blue trace: Without C1, peak-to-peak ≈ 0.25 V around 2.5 V
- Orange trace: With C1, peak-to-peak ≈ 0.10 V around 2.5 V
