METHOD OF VARYING CUTOFF FREQUENCY OF RC FILTERPROBLEM TO BE SOLVED: To provide a low-pass filter, high-pass filter and all-pass filter, comprised of a resistor and a capacitor, capable of changing its cutoff frequency without changing values of the resistor and the capacitor.GOMI SHINTARO...
Formula for cutoff frequency of RC filter circuit An RC filter circuit consists of a resistor (RR) and a capacitor (CC). Figure 2 shows the circuit diagram of a simple low pass RC filter. We know that the capacitive reactance (i.e., the resistance offered by a capacitor to the current...
