#182195 - High pass filter... Responding to: ???'s previous message |
The sensor contains an amplifier. The gain can be configured by R1 and R2. C seems to form a high pass characteristic with a corner frequency of f = 1/2/pi/R2/C. R1 in the given formula is a typo, I guess.
This sensor seems to work with pulsed light, like a chopper. Kai Klaas |

| But gain is different for AC and DC? | 01/01/70 00:00 | |
| C reduces the gain for DC | 01/01/70 00:00 | |
I understood much more about this sensor | 01/01/70 00:00 | |
