2nd-Order Low Pass Filter -3dB Frequency
Above is a formula extracted from electronicstutorials . It refers to a second order low pass filter to calculate the actual cut off frequency for any level (n) of low pass fillers. The normal cut of frequency given by the formula
Can anyone explain this to me , I assume the '1' in the formula is outside the square root symbol?
