WebSep 2, 2024 · The closer the sampling frequency gets to twice signal bandwidth, the longer time is required of the sampled signal. It’s something like : if you oversample by 1% (that is sample rate = 2.02 * bandwidth) then you need something like 100 periods to reconstruct with something like 1% SNR. WebMar 17, 2024 · However, with audio components, the SNR is always a positive value. For example, an SNR of 95 dB, means that the level of the audio signal is 95 dB higher than the level of the noise. Which, in turn, means that an SNR of 95 dB is better than one that is 80 dB.
