COMPUTER NETWORK
A Signal travels from point A to point B. At point A, the signal power is 100W.At point Power is 90 W. What is the attenuation in decibel?
Suppose a signal travels through a transmission medium and its power is reduced to P2=1/4P1.In this case, the attenuation (loss of power) can be calculated.
The signal-to-noise ratio is often given in decibels. Assume that SNRdB =38 and the channel bandwidth is 3MHz. The theoretical capacity can be calculated as.
