What information is present in the A-mode display?

Explanation:
A-mode presents echoes as vertical spikes along a horizontal time axis. The horizontal position of each spike corresponds to how far away that reflector is (depth, since echo time relates to distance), and the spike’s height shows the echo’s amplitude (strength). So the display provides amplitude and reflector distance. Frequency bandwidth or motion pattern aren’t shown in A-mode; those aspects appear in other modes like B-mode or M-mode.
