Low-pass filters (LPF) pass signals from low frequencies and reject signals from high frequencies. Like other types of active filters, they use active components to shape and stabilize the behavior of the filter, and to serve as a buffer interface for the driven component. There are two basic classes of active low-pass filters: switched capacitor and continuous. Each type of device is available with first, second, third, fourth, fifth, sixth, seventh or eighth filter order. Switched capacitor filters are clocked devices. The input signal is sampled at a high rate and processed discretely instead of on a continuous-time basis. Continuous low-pass filters have a continuous time operation.
