Is there a formula to find the db per octave of a low pass filter like this one?


R1

Your extremely simple filter is backwards.
The input is at the resistor on the right.
The output is at the resistor and the capacitor on the left.
Its slope is only 6dB/octave.

I said that the C1 should be to the right of R1
The way to preserve the formatting is to use the code tags:

Code:

                                           --- C1
                                             |
                                             |
                                             |
