Publisher's Synopsis
Excerpt from Theory of Design and Calibration of Vibrating-Reed Indicators for Radio Range Beacons
An interesting application of these results occurs in the 3-reed or 12-course indicator. Because of space limitations in this type of indicator, it is not possible to set the driving coils at the proper posi tions to give equal reed sensitivities for equal gaps. In this case, the distance from the driving pole to the free end of the reed is considered constant and the reed sensitivity varied by moving the base of the reed, thus varying the length and driving distance (mo) simultaneously.
