the extent that it operates under the noise floor
and creates no
If the noise floor
is too low, the dynamic range will often be too high.
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.
The rms noise floor
is a little tricky to measure because of low-level idle tones and, in some converters, muting that is applied when the signal input is zero.
The unit's low noise floor
over a wide frequency bandwidth up 200 kHz makes for exceptional, accurate measurement of dynamic signals.
The series is said to offer the industry's lowest residual noise performance by using dual channel architecture to cancel its internal noise floor
Type 4961, is the only quarter-inch measuring microphone with a 20dB noise floor
and sensitivity exceeding 50mV/Pa.
Internal hybrid signal conditioners to achieve a low noise floor
Aeroflex uses a 'Smart Convertor' scheme in the down-convertor's architecture, claimed to enable a noise floor
performance as low as -168dBc/Hz up to 2GHz.
The M/A-COM series of modulators measures, on average, 8 dB better in terms of output noise floor
than most of its competitors.
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.
