| The response curve generated by the Frequency Domain Simulation plots dBV against frequency, where 0dBV = 1V. Is that 1V an RMS, Peak, or Peak-to-Peak value? I design op-amp circuits here and always set the signal generator model to 1V @ 1kHz for the input signal and know that this 1V is a Peak value. However, the voltage level corresponding to a dBV value is usually an RMS value, according to information I found online. But I could not find that particular specification on the curve generated by the Frequency Domain Simulation at this, the CircuitLab website. Could you tell me what that spec is? Thanks. | by Kurtus October 23, 2025 |
| I am currently assuming that a voltage level corresponding to any dBV value is an RMS value. The normal assumption. But I would like to know for sure that this is true for the response curve given by the Frequency Domain Simulation. A specific answer would be very helpful. | by Kurtus October 24, 2025 |
| I believe I can answer my own question, but would like to follow up with another one. First, I like the online calculator linked here. https://calculator.academy/db-to-voltage-calculator/ For any dB (volts) I enter, it gives corresponding dBV, dBu, dBuV, V, mV, uV, V Peak (sine), V P-P (sine), V/Vo, and P/Po. The text at that site, while giving the formulas used by their calculator, specifies that this V is an RMS value. My question now is: Can I depend on this calculator to interpret the dBV values on the response curve for my op-amp circuits, as generated by the Frequency Domain Simulation? | by Kurtus October 26, 2025 |
