Visualization of Frequency Filters

[linbingkong]

Can you share the code for Visualization of Frequency Filters? I don’t know how this is implemented by performing frequency domain analysis on the predicted data?

Given a filter $H \in R^{1 \times L}$, where L is its bandwidth, we visualize the frequency response characteristic of the filter by plotting the values in $R^{1 \times L}$. First, we perform a Fourier transform on these values to obtain the spectrum, which includes the frequency and
its corresponding amplitude. Finally, we visualize the spectrum. We have introduced the visualization methods in Appendix C.5.
