The dotted horizontal line spanning all months at 71 dB re 1 [micro]Pa is the noise floor
of the recorders, which significantly overlaps with the values for January through March.
Performing a 10,000 trace attack indicates no correlation discernible from the noise floor
. In this scenario, the correlation cannot be distinguished from the noise floor
in the correlation trace; therefore this configuration is declared protected against the 10,000 trace correlation power analysis attack.
The internal noise limits the measurement system noise floor
. The measurement system is passive, with the exception of the amplifiers used after the power detection and the digital processing circuitry.
From this figure, one can see that the mean noise floor
using the design by modulating the transfer function can keep to less than -60dB.
Assertion Two: Signals Below the Noise Floor
If the noise floor
is too low, the dynamic range will often be too high.
"UWB theoretically transmits short pulses across a very wide swath of spectrum, and does this within the noise floor
," noted Gemma Paulo.
The receiver has to have a low "noise floor
," so it can collect these small signals over a wide frequency range.
At lower frequencies, distortion-product otoacoustic emission amplitudes were found to be significantly above the noise floor
in five of the 11 patients whose hearing thresholds were 60 dB HL or worse by click auditory brainstem response testing.
The HP 93000 SOC Series also has a very low noise floor
, which is a key enabler for testing most advanced SOC devices.
Comparison of the noise floor
of our logger and low frequency hearing of the one elephant seal tested suggests that we can hear most everything the seal hears at these frequencies.
The power spectrum of the fiber and the power budget, the difference between the maximum power optical devices can provide and the noise floor
, are shared between the many wavelengths used.
