Low Pass Filter- Explained - Learning about Electronics

WebA low pass filter is a filter which passes low-frequency signals and blocks, or impedes, high-frequency signals. In other words, low-frequency signals go through much easier and with less resistance and high-frequency signals have a much harder getting through, which is why it's a low pass filter. Low pass filters can be constructed using ...
