Reference no: EM131233300
1. Given an amplifier with an effective noise temperature of 10,000 K and a 10- MHz bandwidth, what thermal noise level, in dBW, may we expect at its output?
2. What is the channel capacity for a teleprinter channel with a 300- Hz bandwidth and a signal- to- noise ratio of 3 dB, where the noise is white thermal noise?
3. Given the narrow (usable) audio bandwidth of a telephone transmission facility, a nominal SNRdB of 56dB (4000,000), and a distortion level of <0.2%
a. What is the theoretical maximum channel capacity (kbps) of traditional telephone lines?
b. What is the actual maximum channel capacity?
4. Given a channel with an intended capacity of 20 Mbps, the bandwidth of the channel is 3 MHz. Assuming white thermal noise, what signal- to- noise ratio is required to achieve this capacity?
5. If the received signal level for a particular digital system is -151dBw and the receiver system effective noise temperature is 1500 K, what is Eb/No for a link transmitting 2400 bps?
Explain each answer in detail please, i have grade for explanation also.
