question about Low Pass Filter


Recommended Posts

The 4.7nF capacitor creates a lowpass filter with the unknown value of the source resistance.
The 10k resistor and 6.8nF capacitor create another lowpass filter.

If the cutoff frequency of both filters is the same then their total is -6dB because each filter is -3dB.

If the cutoff frequency of both filters is  not the same? is it sitll -6dB
