National Security Agency encryption devices

KY-58

The VINSON KY-58 is a secure voice module primarily used to encrypt radio communication to and from military aircraft and other tactical vehicles. It is employed by U.S. Military Joint Services, NATO and some law enforcement agencies. It is designed to operate over bandwidth-restricted circuits such as UHF and VHF satellite access and wideband switched telephone systems. It uses the 16 kbit/s continuously variable slope delta modulation (CVSD). The system was initially fielded as a replacement for the KG-36 and KG-34. The unit fits in a five-inch cube and weighs about 5 pounds. Production ended in 1993. (Wikipedia).

Quickly fill in the unit circle by understanding reference angles and quadrants

👉 Learn about the unit circle. A unit circle is a circle which radius is 1 and is centered at the origin in the cartesian coordinate system. To construct the unit circle we take note of the points where the unit circle intersects the x- and the y- axis. The points of intersection are (1, 0
