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.
The distance formula is derived from the Pythagorean theorem. Distance between two points in a plane is calculated with the 2 coordinates (x1, y1) and (x2,y2). Draw a right angled triangle with the line formed by the points. The distance between the two points can be calculated by finding the horizontal (x2 - x1) and vertical distances (y2 - y1). Enter the coordinate values into this online Distance Between Two Points Calculator and find the length between the two points.
