In this article, we will discuss the fact that choice of different window functions involves a trade-off between the main lobe width and the peak sidelobe (PSL). To gain more insight, we will calculate the Fourier transform of a triangular window using the Fourier transform of a rectangular window. The connection between these two windows helps us to better understand the aforementioned trade-off.
