A pilot becomes skilled when he/she

- The systematic alteration of the parameters of a signal is called: Modulation.

- The following figure represents the spectrum of a modulated signal: Amplitude

- Notes which is the misstatement: The FM modulation is more sensitive to noise

- The MPX signal is the set of the following: total R & D, ID-modulated DBL, pilot and RDS data signal if necessary

- Report incorrect statement which is one of the following with respect to the ROE would have a team of transmission when connected to the antenna: If the impedance of the transmitter is smaller than the antenna no problem
- In a station, connect the antenna to measure the VSWR value of what will be following the best ROE factor?: ROE = 1.1
- The intermediate frequency in a receiver is: Always the same and allows better reception with the heterodinación.
- Where P _TX (transmitter power), G _ANT (antenna gain), PRA (radiated power) and At _ACC (accessories attenuation) What is the correct formula?:
P _TX = PRA - G _ANT + At _ACC.
- The PLL (Phase Lock Loop) is a device used for the following in a radio: Get the VCO has the precision of a quartz crystal.
- Indicate which is the INCORRECT statement regarding DAB digital radio system. The band that uses DAB radio emission is the same as the FM (88-108 MHz).

item 5:
- In the diagram below the numbered items in ascending order, are: Center issuer central control booth.

- In a radio station, where will centralize all the signals generated in different production studios programs: In central control. "The central element of the production control is: The patch panel.
"In the parlor of a radio station, monitoring is more appropriate: For headphones.
"The external signals are received at the production control through: The auxiliary lines." The patch panel is a computer that is generally, in: The central control.
RDS-generator is responsible for: Generating station information and programming the same.
- Which statement is incorrect?: The system emits radiant form omnidirectional radio link.
- Put the missing names on the following computers:

- In the technical documentation of a radio station, the document that defines the actions to take to revise the system is: The verification protocol

- In the diagram below the numbered items in ascending order, are: Center issuer, parlor, production control.

- To connect multiple headphones to monitor the same line we use: A distributed audio. - In a radio station, the computer that contains the identifying of the same tunes is called: signal source reserve.
- The team responsible for generating station information and programming the same is called: RDS generator.
-To reduce the dynamic range of the audio signal before it is issued is used: A compressor.
