# Long description

This figure consists of two graphs of signal strength against frequency. Each one has a wider rectangle representing interference and a smaller rectangle of the same height representing the wanted signal; these two rectangles are shown side by side on the horizontal axis with a gap in between them. In graph (a), the interference is at a lower range of frequencies than the wanted signal, while in graph (b), the interference is at a higher range of frequencies than the wanted signal.
