Indeed, the noise floor
of the fly-inspired microphone is about 17 decibels lower than what can be achieved using a pair of low-noise hearing aid microphones to create a directional hearing aid.
Spectrum below the noise floor
is therefore not scarce, at least
In these patients, emission amplitudes were above the noise floor
at all frequencies between 500 Hz and 8 kHz, and these responses were accepted by the system as valid.
All systems use HP's third-generation Test Processor-per-pin technology for the highest throughput and a low noise floor
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.
The C360659-UV-1 offers high responsivity at 500 nm with a very low noise floor
The AD9625 provides better noise and dynamic range performance -- a 150 dBFS/Hz noise floor
and 80 dBc SFDR out to Nyquist.
Additional software options are available to measure AM noise floor
and signal statistics such as HDEV, TDEV, MDEV and jitter, and for use as a frequency counter and for mask testing.
Typical noise floor
is 150 ig/rt-Hz, allowing signals below 1 mg (0.
The magnetic noise is measured by subtracting a reference spectrum, in which the magnetization is saturated with a large field, from the noise spectrum This subtraction allows the magnetic noise to be separated from other noise sources and gives a noise floor
of 5 pV/[Hz.
The energy of multiple pulses from different devices stepping on one another, were they to occur in the same instant in time, can have a cumulative effect and potentially bring their cumulative energy out of the noise floor
Designed for TETRA use in the 200 to 600 MHz band, the RF2485 features a broadband noise floor
of -149 dBm/Hz typical at 5 MHz offset along with ACPR of -48 dBc typical at 25 kHz.
