A series RC circuit consists of a voltage source, a capacitor, and a resistor. RC circuits can be used to filter an alternating signal by blocking certain frequencies and allowing others to pass. The most common RC filters are the high-pass filter, low-pass filter, band-pass filter, and band-reject filter. RC circuits are characterized by being linear and time-invariant systems. In this video I will show you how to analyze them using the Laplace transform.
