Aircraft Radio Terminology Crossword

The faithful reproduction of a signal
A series LC circuit makes this type of filter
VHF radio signals propagate in this manner
To block certain frequencies
This amplifier produces pulsating DC and is usually only found in RF circuits
The frequency at which XL and XC are equal and opposite
The field of electric and electromagnetic energy that carries the intelligence of a radio signal
This produces a frequency that gets mixed with an RF signal in a radio receiver
This system is used to help aircraft find a runways' centerline
This type of circuit can be an oscillator, or a band reject filter
The ability of a radio receiver to pick up very weak signals
The opposite of fidelity
The radio receiver that really made a difference!!!
To broadcast or send out
Superimposing an audio signal onto a carrier wave by changing the cycles per minute
For an antenna to work well with a radio, this has to match
HF radio signals propagate in this manner
This filter has an inductor in series and/or a capacitor in parallel
This type of amplifier has the lowest efficiency but the highest fidelity
The ability of a receiver to tune in to a specific frequency, while blocking adjacent frequencies
The exchange of information
This component radiates energy in the form of electro-magnetic waves
This component is also called a "Coil" or a "Choke"
The process of super-imposing information on to a carrier wave
This amplifier is biased AT the cutoff point
The circuits in a superheterodyne are tuned to this frequency
A device that converts radio waves into intelligible sounds
