Passive Low Pass Filter
This means that the voltage potential, V C across the capacitor will be much larger than the voltage drop, V R developed across the resistor. At high frequencies the reverse is true with V C being small and V R being large due to the change in the capacitive reactance value.
Low Pass Filter
So, with this setup, the above circuit is a low pass filter. As a capacitor is a reactive device, it offers differing resistance to signals of different frequencies entering through it. A capacitor is a reactive device which offers very high resistance to low-frequency or DC ...
