WebFeb 2, 2024 · Depending on the configuration, you can use the RC filter to either filter out low or high frequencies. These are the high pass and low pass filters. If you combine a low pass filter with a high pass filter, you get a broadband filter that suppresses all the signals below and above some frequencies. By viewing the circuit as a voltage divider, the voltage across the capacitor is: and the voltage across the resistor is: The transfer function from the input voltage to the voltage across the capacitor is Similarly, the transfer function from the input to the voltage across the resistor is
