Use of CSB/SBO technique in the Instrument Landing System (ILS)
How the space modulation of the localizer transmission of the ILS is accomplished, using the CSB (Carrier & Sidebands) and SBO (Sidebands only) technique. Includes sum & difference technique, some information about DSBSC signals and relevant antenna theory and application, in particular broadside antennas fed in antiphase. Note: Subtitles added in English (UK)
