Compared to the Note 5, the S Pen in the Note 8 has enhanced levels of pressure sensitivity (4,096 distinct levels of pressure), [8] though The Verge noted that those enhancements were featured in the defunct Note 7. [5] Ports include a 3.5 mm headphone jack and a USB-C port for charging and data transfer. [5]
Form factor: Slate: Colors: Note 7/Note FE: Blue Coral, ... The Note 7 stylus supports 4,096 levels of pressure sensitivity and is water resistant. [10] Camera
The Galaxy Note 7's display is curved across the sides of the device, and its stylus features higher degrees of pressure sensitivity (4096) and a finer tip. [22] [23] Samsung branded the device as the Note 7 rather than the Note 6 in order to synchronize its branding with the earlier flagship of the same year, the Samsung Galaxy S7 series. [24]
In some literature, the name sensitivity is used for this concept. [1] When the resulting signal is then interpreted by a human operator, as in radar systems, the related term minimum discernible signal may be used. This includes additional factors like clutter and the lifetime of the signal on the radar display.
The sensitivity of a microphone is usually expressed as the sound field strength in decibels (dB) relative to 1 V/Pa (Pa = N/m 2) or as the transfer factor in millivolts per pascal (mV/Pa) into an open circuit or into a 1 kiloohm load. [citation needed] The sensitivity of a loudspeaker is usually expressed as dB / 2.83 V RMS at 1 metre.
[a] A more precise model known as the Inflected Exponential function, [3] indicates that loudness increases with a higher exponent at low and high levels and with a lower exponent at moderate levels. [4] The sensitivity of the human ear changes as a function of frequency, as shown in the equal-loudness graph. Each line on this graph shows the ...
Furthermore, modern devices often use a feedback mechanism to monitor and adjust the sound pressure level in the cavity so that it is constant regardless of the cavity / microphone size. Sound calibrators normally generate a 1 kHz sine tone; 1 kHz is chosen since the A-weighted SPL is equal to the linear level at 1 kHz. Sound calibrators should ...
A graph of the A-, B-, C- and D-weightings across the frequency range 10 Hz – 20 kHz Video illustrating A-weighting by analyzing a sine sweep (contains audio). A-weighting is a form of frequency weighting and the most commonly used of a family of curves defined in the International standard IEC 61672:2003 and various national standards relating to the measurement of sound pressure level.
