PNP is a signal processing software that lets users manipulate the poles and zeros of a one-dimensional digital filter. It is a free, open-source program designed for tutorial purposes and provides visualizations of the filter's effects in the frequency domain.
One of the main things that PNP allows you to do is to set, move, and remove poles and zeros of a one-dimensional digital filter. This feature can be incredibly useful when it comes to manipulating signals, and can help users to better understand how digital filters work in general.
Finally, PNP is also capable of displaying a range of different effects of the filter in the frequency domain. This can help users to better visualize how their changes to the filter are affecting the overall signal, and can lead to a deeper understanding of how digital filters work. Overall, PNP is an excellent choice for anyone who is looking for a powerful and accessible tool to help them learn more about signal processing.
