Any audio that you hear on an AM receiver is from the two sidebands. When the radio transmitter you are tuned to is not transmitting any sound, you can still hear from the speaker and see on your S meter that a signal is present due to the background noise being quieter than either side of that frequency.

How to calculate Perpendicular distance between a point and a line The perpendicular distance (d) of a line Ax + By+ C = 0 from a point (x1 ,y1) is given by d = | Ax1 + by1 + c|/ root (A^2 + B^2) complete explanation of formula and solved example. 1  Education. 2  Standard YouTube License.
From Latin: perpendicularis vertical, as a plumb line. A line is perpendicular to another if it meets or crosses it at right angles (90Â°). Try this Drag the orange dot at point A. The line AB will be perpendicular to DF only when it meets it at 90Â°. Perpendicular means at right angles.A line meeting another at a right angle, or 90Â° is said to be perpendicular to it. In the figure above, the line AB is perpendicular to the line DF.rom Latin: perpendicularis vertical, as a plumb line.
