Wireless Audio Cable - Functional Description
Our senior project goal is to design and build a wireless audio cable
replacement. The end
result should be a product that will allow the user to input an audio signal from the audio source
of their choice (CD player, computer, etc.), and output it to speakers in a remote location.
The audio signal is a stereo signal with left and right channels, and has the equivalent
sound quality of a CD player.
we will divide our project into more than one item
1.Audio signal charactrestic
."amplitude, phase,frequency...............".
.
rating power.
rating current.
2.What is the meaning of "signal conditioning"
.Available signal conditioning circuits.
3.COMPRESSION &EXPANSHION
.why compression &expanshion ,type of them
.Available circuits or "integerated circuit".
.rate of compression.
4.Transmation &Receiving Stages
.available circits"vco"
.why "vco"not ather
.IF"vco"566 available or not""
.diffrence between {vco"566"&vco"4024 IC"}
.Why FMnot AM?
5.ANTENNA&WAVE
PROPAGATION a.which types of wave propagation
1.Ground wave propagation
2.Sky wave propagatio
3.line of sight wave propagation
b.coverage area&power density
c.which type of antena?why
d.charactrestics of Air
6.AMPLIFIERS&SPEAKERS
.WHICH TYPE OFAMPLIFIERSACOORDINR TO "CLASS"
.What is variable gain amplifier
.rating power
.speakers charactrestics
7.TESTING&EXPERIMENTAL RESULTS
.Sound Quality
.Senstivity
