Results
| Metric | Value |
|---|---|
| Passband gain | 1.999995 V/V |
| Passband gain | 6.020578 dB |
| -3 dB cutoff frequency | 998.596 Hz |
| Gain at 1 kHz | 3.014511 dB |
- The filter gives a passband gain of essentially 2 V/V
- In dB, that is 6.02 dB
- The -3 dB cutoff is essentially 1.00 kHz
This matches the expected design very closely:
- Closed-loop gain: (1 + 10k/10k = 2)
- Pole from (15.9k) and (10 nF): about 1 kHz
If you want, I can also give you:
- the transfer function
- the exact SPICE-style circuit description
- a comparison against the theoretical calculation
