state the meaning of the terms processor , output device and feedback

I don't know the exact definitons but i can explain to you how they are related in a circuit .Hopefully you'll get the meanings.

A microphone produces a signal . A Processor (in this case a potentiometer ) receives this signal. It checks the input ( received ) value against it's own preset-value and emits a signal according to the frequency of the received signal . An Output Device ( in this case a speaker) receives this signal and produces sound .

Feedback : The part of the output signal which is provided back to input for further processing .

Hope This Helped.

thankuu soo much!!!..and so the processor is something that analizes the input and sends it to an output device and an output device is which produces a resultant signal etc and feedback is sending this output signal back to the processor??...m i rite??

well for underground lines, you have to dig alot and for long distances so that is expensive and when digging is done obviously nature is disturbed...
thus underground lines are much more expensive compared to the overhead lines and the overhead lines have a much less environment issue than the underground lines, as well know that digging is considered as pollution!! :D
