Welcome to your Modulation
What type of device can be used in balanced modulators?
Which of the following is not an advantage of FM over AM?
The bandwidth in _____ depends on the number of significant sidebands
In what classes are SSB linear amplifiers operated
Refers to the first symbol in an emission designation with an amplitude modulated main carrier represented by letter A.
In the designation of bandwidth and emission, what letter in the symbol represents a double-sideband of modulation
In AM, maximum desirable output of a transmitter is obtained when its modulation is _____%.
A circuit often used in radio receivers that prevents externally generated noise from exceeding certain amplitude. They are also called noise clippers.
The power in FM _____ as the modulation index increases.
What is the major advantage of FM over AM?
A method of generating SSB signal; that utilizes only one balanced modulator circuit
A form of single sideband emission where the degree of carrier suppression enables the carrier to be reconstituted and be used for demodulation
What is the result of overmodulation of an FM emission?
For _____ percent modulation in AM, the modulation envelope has a peak value double the unmodulated carrier level.
What pattern of modulation must used when neutralizing an operating transmitter?
An indirect method of generating FM is a
What is the main problem in receiving a suppressed carrier transmission or a single sideband transmission?
The modulation index of an AM wave is changes from 0 to 1. The transmitter power is?
What produces splatter in an AM transmission?
If a 7-A carrier is modulated 100% by a sinusoidal tone, how much does the antenna current increase?
