Part 2 - VIVA Flashcards
Contains both DGCA and WPC
What is Frequency?
Frequency describes the number of waves that pass a fixed place in a given amount of time.
Frequency is Denoted by: Hz
What is Fading of a Frequency?
Fading occurs when both signals are received both by Ground wave and Sky wave paths.
The signals combine with each other to disrupt and fade away.
Fading an occur due to Weather conditions, Objects and Time of Day.
What is Attenuation?
The gradual declination of Electromagnetic due to Weather, Obstacles like Lead that absorb Electromagnetic Waves and even the Atmosphere doing different times of the day.
What is a Sine Wave?
A sine wave is a wave form whose shape is that of a Trigonometric Sine function.
What is a Carier Wave?
A career wave is an Information wave that is sent by the help of superimposing it with the Modulation Frequency.
What is Suppression of Carier Wave?
Suppression of career wave is a method of modulation where the carrier Signal is suppressed and not shown on the Output.
Types of Modulations.
Continuos wave Modulation - Amplitude Modulation, Frequency Modulation and Phase Modulation
Pulse Modulation (Analogue) - PAM, PQM and PPM
What is AM? Its Advantages.
AM is where the Amplitude is varied along with the Carieer Wave.
The Advantage of AM is that it forms SSB and DSB which can give more options in the amount of information passed, Range, Spectrum and Power required.
What is FM? Its Advantages.
FM is where the Frequency is varied along with the Carrier frequency but the Amplitude remains the same.
The Advantage of FM is it has an improved signal to noise
What is Pulse Modulation? Its Advantages.
Pulse modulation is a part of an Analogue signal where the signal gives out pulses in 0s and 1s.
What is Phase Modulation? Its Advantages.
Problems regarding Frequency in an Aircraft.
What is Attenuation?
It is the loss of Radio Signal strength as it travels away from the TX. Occurs due to absorption from atmosphere.
What is Garbling?
k
What is Fruiting?
What is Interference?
What is Flux?
The amount of Energy/Charge that passes though a give point per unit time.
