Web13 apr. 2024 · In addition, the additive noise usually consists of both shot and thermal noises, and it is generally reasonable to model the additive noise as a real-valued zero-mean additive white Gaussian noise (AWGN) with power σ 2 = N 0 B, where N 0 is the power spectral density (PSD) of the AWGN and B is the signal bandwidth . WebThe noise floor, also known as additive white Gaussian noise (AWGN), is a continuous noise level that appears over a wide spectrum when viewed in the frequency domain. True False 10 points Question 2 When considering the impact of impulse noise, we find that it is more devastating to a digital communications link, than an analog one.
