<span>UHF and HF technology enables afloat forces to communicate more securely and to operate in a more dispersed manner.
</span>UHF stands for Ultra High Frequency, while HF stands for <span>High Frequency .
</span>The UHF range of the radio spectrum is the band<span> extending from 300</span>MHz<span> to 3 GHz and </span>is extensively used for satellite<span>communication and broadcasting, in </span>cellular telephone<span> and paging systems, and by third-generation (</span>3G<span>) </span>wireless services.
Answer:
135 minutes or and 2 hrs and 15 minutes
Only B and C would be the best choice
Answer: a) Single-bit errors: It affects only one bit in a symbol.
Burst errors: It affects to several sequential bits in a given
symbol
b) 10000 bits.
c) When the most typical error is a single bit error.
Explanation: a) It is explained in the answer.
b) If data is being transmitted at 100 Mbps, this means that in 1 second, 100x 10e6 bits are transmitted, and that one single bit lasts for 10e-8 sec.
So, if the noise event that causes the burst error lasts 0.1 msec, this means 10e-4 sec.
Number of bits in error= 10e-4/10e-8= 10e4 bits= 10000 bits.
c) If the error is in a single bit in a symbol, this means that if the right number of 1s is even, a single error will change this number to an odd number , and the error could be easily detected.
