Filters are electronic components designed to selectively allow or block certain frequencies or ranges of frequencies in a signal or waveform. They are used to remove unwanted noise, interference, or specific frequency components, and to shape or modify the frequency response of a circuit or system. Filters can be classified into different types, such as low-pass, high-pass, band-pass, and band-stop filters, each serving specific purposes in applications ranging from audio and communication systems to power electronics and signal processing.
