Overmodulation  
 


Overmodulation


Overmodulation is the condition that prevails in telecommunication when the instantaneous level of the modulating signal exceeds the value necessary to produce 100% modulation of the carrier.


Overmodulation results in spurious emissions by the modulated carrier, and distortion of the recovered Overmodulation modulating signal.


Overmodulation in the sense of this definition is almost always considered a fault condition. If defined as, the condition that prevails when the mean level of the modulating signal is such that peaks in the modulating signal exceed the value necessary to produce 100% modulation of the carrier, overmodulation is sometimes considered permissible.

Electronics Topics

The field of electronics is the study and use of systems that operate by controlling the flow of electrons or other electrically charged particles in devices such as thermionic valves and semiconductors. The design and construction of electronic circuits to solve practical problems is part of the fields of electronic engineering, and the hardware design side of computer engineering. The study of new semiconductor devices and their technology is sometimes considered as a branch of physics.
