EAGLE is a scriptable electronic design automation (EDA) application with schematic capture, printed circuit board (PCB) layout, auto-router and computer-aided manufacturing (CAM) features. EAGLE stands for Easily Applicable Graphical Layout Editor (German: Einfach Anzuwendender Grafischer Layout-Editor) and is developed by CadSoft Computer GmbH.
Claris CAD uses a drawing system defined by Tools, Methods, and Modifiers. Tools draw objects, methods allow different ways of drawing with the tools, and modifiers help to position objects. [3] Some notable tool functions include: walls, arcs, chamfers, fillets, spline curves, perpendiculars, and tangents. Dimensioning tools can create point ...
Schematic capture or schematic entry is a step in the design cycle of electronic design automation (EDA) at which the electronic diagram, or electronic schematic of the designed electronic circuit, is created by a designer. This is done interactively with the help of a schematic capture tool also known as schematic editor. [1]
The AN/ART-13 operated in CW (code), MCW and AM (voice) modes and covered LF, MF and HF frequencies up to 18.1 MHz.It had ten autotuned VFO tuned channels that could be preset. . Post-war modifications by COMCO and other companies added crystal frequency control capability and were approved for use on civil airline

In TV transmitters, both AF and VF modulate intermediate frequency (IF) carriers. (The frequency difference between the two carriers is 4.5 MHz in System M and 5.5 MHz in System B/G ) Then the modulated IF signals are added either at the output of the vision modulator or at the output of the vestigial sideband stage.
Multichannel Television Sound (MTS) is the method of encoding three additional audio channels into analog 4.5 MHz audio carriers on System M and System N.The system was developed by an industry group known as the Broadcast Television Systems Committee (BTSC), a parallel to color television's National Television System Committee, which developed the NTSC television standard.
B-MAC [1] is a form of analog video encoding, specifically a type of Multiplexed Analogue Components (MAC) encoding. MAC encoding was designed in the mid 80s for use with Direct Broadcast Satellite systems. Other analog video encoding systems include NTSC, PAL and SECAM. Unlike the FDM method used in those, MAC encoding uses a TDM method.
