What is the formula to find approximate value of cutoff frequency of Butterworth filter ?Select one:
Solution
To find the approximate value of the cutoff frequency of a Butterworth filter, you can use the following formula:
fc = 1 / (2 * π * R * C)
Where:
- fc is the cutoff frequency in Hertz (Hz)
- π is a mathematical constant approximately equal to 3.14159
- R is the resistance in ohms (Ω)
- C is the capacitance in farads (F)
By substituting the appropriate values for R and C into the formula, you can calculate the approximate cutoff frequency of the Butterworth filter.
