Hi,
I have 1 homework problem which I just dont understand... All the terms are confusing me.
A transmission medium has a -3dB per 100-meter attenuation characteristic. The receiver on one end of the medium can correctly interpret signals if the signal to noise ratio is above 20dB. What initial signal level is necessary to allow for transmission over 1km?
So how shld i go about? Any hints will be appreciated...
