Three types of EMI:
+++++ interference impedes the reliable and efficient use of electrical and electronic equipment.
+++++ interference consists of a single frequency or a narrow band of frequencies that occupies little space in the total receiver passband.
+++++interference occupies a relatively large part of the radio frequency spectrum.
++++++ interference, such as that caused by electrical storms, snowstorms, rain particles, or interstellar radiation, is referred to as atmospheric noise or static.
Interference is transferred from an interfering source to the affected equipment by two general methods:
+++++ is any interfering signal transferred through space by an electromagnetic field
+++++ are recognized by their distribution across a wide portion of the tuning range of the affected receiver
Military specifications require that the second harmonic level be at least ++db below the fundamental
Third and higher order harmonics must be at least ++ db below the fundamental
++++++ cause emissions at radio frequencies which are neither harmonics of the fundamental nor inter-modulation product frequencies.
++++++ occur when a circuit is self-excited and goes into oscillation at a frequency other than the desired one.
_______is the transfer of modulation from one carrier to another
+++++ is the generation of numerous new frequencies from two or more original signals.
++++++ occurs when the center frequency, or carrier of an undesired signal, falls in any portion of the passband of another receiver.
+++++++ occurs when a strong unwanted signal penetrates the input filter circuits and encounters a nonlinear element such as the mixer of an overloaded RF amplifier stage.
++++++ occurs when internally or externally stressed metals are exposed to a corrosive environment.
Signals, created by nonlinear junctions in the ship structures, are commonly called the +++++
rusty bolt effect
Arcing can occur inside of waveguide causing a high voltage standing-wave ratio (VSWR) due to:
• Foreign objects (including moisture) in the waveguide
• Corroded or flaked-off coating
• A sharp bend in the waveguide run
Arcing may result when a radar rotary joint is:
Interference between radars usually appears as a series of moving dots, or ++++++on the CRT
Two general techniques for bonding:
direct and indirect
++++ bonding is achieved by direct metal-to-metal contact between two metal items through the process of welding or brazing.
++++++ bonding is achieved by the use of a bonding jumper or bolts between two metal items.
