MT-003
了解SINAD、ENOB、SNR、THD、THD + N、SFDR，不在噪底中迷失。用于定量表示ADC动态性能的常用指标有六个，分别是：SINAD(信纳比)、ENOB(有效位
数)、SNR(信噪比)、THD(总谐波失真)、THD + N(总谐波失真加噪声)和SFDR(无杂散动态
范围)。(Learn SINAD, ENOB, SNR, THD, THD+ N, SFDR, lost not noise floor. For quantitative expression commonly used indicators of the dynamic performance of the ADC six are: SINAD (SINAD), ENOB (effective number of bits) and SNR (signal-to-noise ratio), THD (total harmonic distortion), THD+ N ( The total harmonic distortion plus noise) and SFDR (spurious-free dynamic range).)

(An optical fibre evanescent field sensor for methanol
(CH3OH) and ethanol (C2H5OH) solvents based on deformed optical
fibre cores is reported. The sensitivity of an existing U-bend
probe is increased by extending the exposed core to a coil shape
of one and a half turns and by forming the core to a meander
shape with three bends. Using the visible wavelength area (VIS)
and methanol/ethanol concentrations from 0 to 10 it is shown
that the sensitivity of the meander shape sensor enables the determination
of methanol concentrations of better than 0:5 and of
ethanol concentrations of better than 0:2 at 650nm. This facilitates
the use of low cost optical sources and receivers provided for
this wavelength range as well as the utilization of polymer optical
fibres to guide the light to and from the sensor which results in low
cost applications compared to all silica or polymer clad silica fibre
solutions in the near-infrared (NIR) or ultra-violet (UV) wavelength
range.)
