What is the effective Temperature (T. (K) for a system with a 28 dB input SNR and a 24 dB output SNR? BIVAAI EIX X. - V G T 12pt - Paragraph -
Consider a channel with a bandwidth of 1MHz with SNR of 35 dB 1) what is the maximum bit rate to achieve any arbitrarily small errors 2) what will be the band rte if 16QAM is used? 3) what will be the band rate if 1024 QAM is used?
Determine the bandwidth for a communication channel that has an SNR of 35 dB and capable of transmitting the data rate at 37.2 Kbps.
Calculate SNR(dB) given a noise voltage specification of 500.5nV/sqrt(Hz), used over an audio frequency range of 20Hz to 20kHz, with a voltage gain of 55dB. The output voltage is 1.75 V. Calculate the noise voltage specification given SNR(dB) = 150dB using the same output voltage, frequency range, and gain as in number 3.
4. (5 pts) Suppose that the SNR at the receiver of a communication system is-10 dB. If the noise power at the receiver is 5000 × 10-9 W, calculate the signal power (in μW) at the receiver. 5. (5 pts) Assume we have two communication systems, A and B. Suppose SNRA-5, SNRB10 and BA 600 kHz. What is the required channel bandwidth for system B in order to achieve the same maximum transmission rate as system A?
3. The quality of a received signal is often characterized by the signal-to-noise-ratio (SNR), which is defined as SNR 10 log As you might expect from this Signal power in watts KTB definition, the unit of SNR is decibels (dB). The term in the denominator is the noise power, and it is generally specified as an effective noise temperature T multiplied by the product of Boltzmann's constant (K) and the bandwidth (B) of the signal in Hz. Generally we like...
