An RC low pass filter, also known as an integrator circuit, allows low frequencies to pass and blocks high frequencies. Conversely, an RC high pass filter blocks low frequencies and allows high frequencies to pass through the filter circuit (past the cut-off frequency).
To obtain a band pass filter in an RLC circuit, you can combine a low pass and a high pass filter. For example, in an RC circuit with R=10kΩ and C=47nF, the cutoff frequency is 338 Hz. You can arrange the components as shown in Figure 6 to create a band pass filter.
RC band pass filters are the kind of frequency filter which only allows a band of frequency to pass through and attenuates the rest. These filters are very useful in audio crossover filters, where only a specific range of frequencies is passed to tweeters, mid-range drivers, woofers, and sub-woofers.
For the RC circuit, when the output is taken across the resistor, we have a High Pass filter. By contrast, when the output is taken across the capacitor, we obtain a Low Pass filter.
The cutoff frequency of an RC filter is calculated using the formula: f3dB = 1 / (2πRC). Here, C is the capacitance of the capacitor. An RC filter blocks low frequencies and allows high frequencies to pass through. The Bode plot of a high-pass filter shows its frequency response.
To use our RC filter calculator, input the resistance of the resistor and enter the capacitance of the capacitor. The calculator will then automatically determine the cutoff frequency of the filter circuit.
