Frequency Modulation AM and FM

With the uses of digital data, the understanding of the basic modulation is required. How does the digital bus carries the data?. Due to this need, I include the learning on the subject from the video produced by the US Department of Defense. The videos produced of the Department are well researched, prepared and intended for training purposes.

  

AFDX Card

AFDX is the acronym for Avionics Full Duplex Switched Ethernet. It is based on the on the shelf commercial ethernet technology with the modification to increase its reliability and deterministic making it relatively on-time.

The picture on the left gives example of the AFDX card supplied by the manufacturer.

The followings are the information supplied by the manufacturer.


1. It is On-board AFDX® protocol stack implementation
2.  Airbus and Boeing AFDX® compliant protocol stack
 3. Two full duplex AFDX networks that can be operated in either independent or dual-redundant mode
 4. Comprehensive error injection/detection, filtering and triggering features
 5. Applicable on PCI, cPCI, PXI, PCIe & VME hardware platforms
 6. Driver & API support for Windows, Linux or VxWorks

The picture is given to improve the understanding of the networking system used on the aircraft.

Module 6. 11 Electrical Cables and Connectors

Module 6 is about materials and hardwares and the part 6.11 is on the electrical wires and connectors.

The syllabus gives a brief description of the contents:

A. Wires and cables
- types, construction and characteristics.
- high tension and co-axial cables
- current and voltage rating

B. Connectors
- types, pins, sockets, plugs, coupling, identification codes,

C. Termination, connections.
- lugs, inline splice, pins and sockets.


To help me in planning for the course and to be a guide for the students, I normally prepare a mindmap scatches.

I hope the mind map will help the students to judge the contents and prepare for the course.
