Определение noise floor в Английский Язык Английский Язык словарь

The inherent noise of a circuit or system that establishes the lowest signal level usable

The minimum discernible signal that can be detected by a receiver

A measure (usually in decibels) of the constant level of noise present in all communication channels and systems

The level of noise that an audio device produces, measured in negative dB The lower the dB level, the quieter the device is

That amplitude threshold in a frequency domain instrument below which the presence of a signal will not be measurable (discernible) For example, if the noise floor of an instrument is -75 dB, a signal at -78 dB will be buried in the noise, and not be measurable

The noise value in the signal-to-noise (SNR) ratio for an environment In general, the higher the noise floor, the more sensitive the engine will be to background noise

The noise floor of a device or system is the amount of noise generated by the device itself with no signal present, it is measured in decibels All electronic devices will generate a certain amount of noise, even a piece of wire! Minimizing the noise floor leads to expanded dynamic range, and cleaner recordings or sound production

The inherent background noise level in an audio signal Poor-quality audio equipment produces a higher noise floor

The term suggests that there is always a noise background present in an audio signal The main audio source is then perceived as something "floating" on top of the noise With a reasonable noise level, however, a signal source like a narrated voice should stand completely clear from the nose, i e stand on top of the noise floor

in CDMA refers to the part of the incoming signal which is unusable The primary component of the noise floor on the forward link is signals being sent by the cell to other phones in the same sector, and to a lesser extent other nearby cells and sectors transmitting to their phones The primary component of the noise floor on the reverse link is other phones transmitting to this cell or to others nearby
