High-pass filter - Wikipedia
The simple first-order electronic high-pass filter shown in Figure 1 is implemented by placing an input voltage across the series combination of a capacitor and a resistor and using the voltage across the resistor as an output. The transfer function of this linear time-invariant system is: () = +.The product of the resistance and capacitance (R×C) is the time constant (τ); it is inversely ...
