High Pass Filter- Explained - Learning about Electronics

High Pass Filter- Explained. A high pass filter is a filter which passes high-frequency signals and blocks, or impedes, low-frequency signals. In other words, high-frequency signals go through much easier and low-frequency signals have a much harder getting through, which is why it's a high pass filter.[...]

Filter (signal processing) - Wikipedia

In signal processing, a filter is a device or process that removes some unwanted components or features from a signal.Filtering is a class of signal processing, the defining feature of filters being the complete or partial suppression of some aspect of the signal.Most often, this means removing some frequencies or frequency bands. However, filters do not exclusively act in the frequency domain ...[...]
