You are repairing a guided transmission system made up oftransmitter module, coaxial link and a receiver. The receiver'serror rate has jumped dramatically recently after an electrical storm when several repairs were made to the system. The system's bandwidth B = 1 MHz and the noise density at the receiver is knownto be 1x10 to the negative 8 watts/Hz. For proper operation of thelink, the SNR db at the receiver must be at least 12 db.
a. What is the required signal power at the receiver forproper operation of the link?
b. For this SNR, what is the capacity C of the link in bits/seconds.
c. The transmitter module is specified to have an outputpower of 10 watts. For the coaxial link, what is the maximum distance allowed in kilometers between the trasmitter and receiver?
