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 dimensions of the rectangle are found by calculating the distance between various corner points. Recall that we can find the distance between any two points if we know their coordinates. (See Distance between Two Points) So in the figure above: 1  The height of the rectangle is the distance between A and B (or C,D).2  The width is the distance between B and C (or A,D). 3  The length of a diagonals is the distance between opposite corners, say B and D (or A,C since the diagonals are congruent).ut if the sides of the rectangle are parallel to the x and y axes, then the calculations can be a little easier. In the above figure uncheck the rotated box to create this condition and note that: 1  The height is the difference in y-coordinates of any top and bottom point-for example A and B.
