Communication channel: 100 kHz bandwidth.
a) if I want to transmit a data rate of 8.3 Mbps, what is the minimum signal-to-noise ratio in dB required to do this?
SNRdB = 10log10 (SNR)
C =B log2(1 + SNR)
8.3 Mbps = 500 000 log2 (1 + SNR)
SNR = ?
SNRdB = 10log10 (SNR)
SNRdB = 10log10 (SNR ??)...
Communication channel: 500 kHz bandwidth.
a) if want to transmit a data rate of 8.3 Mbps, what is the minimum signal-to-noise ratio in dB required to do this?
b) If the effective data rate is 80% of the maximum channel data rate.
What is ratio of signal energy per bit to noise power density...
The thermal noise power of a channel with a bandwidth of 400 kHz is 1.776 x 10–15 watts, what is its operating temperature in ℃?
N = kTB
N = thermal noise in watts
k = Boltzmann’s constant = 1.38 x 10-23
T = Temperature in kelvin x + 273
T = N / kB
N = 1.776 x 10^-15
k = 1.38 x 10^-23
B =...
