Chapter 1
between the mea whether it is constant or not along the measurement range.
y=f(x), the sensitivity S(xa) at point xa is:
Resolution（分辨率）:
the minimal change of the input necessary to produce a detectable change at the output
Threshold（阈值）:
the minimal input necessary to produce a detectable change at the output.
Linearity （线性度）：
Closeness between the calibration curve and a specified straight line.
Hysteresis（滞后）：
the difference between two output values of successive input values.
spectrum density of resistor thermal noise in case of open circuit and load matched.
spectrum density of flicker noise.
1/F的噪声
definition of dynamic error?
The dynamic error is the difference between the indicated value and the true value for the measured quantity, when the static error is zero.
6. What are the conditions for a signal transmitted through a linear system and remain undistorted And what are the requirements on amplitude and phase frequency response of sensors in order to avoiding signal distortion
amplitude-frequency=1 phase-frequency is linear the same group velocity and group delay
definition of rising time.
rise from 10% to 90% of the final output value.
to calibrate a sensor.
rate, reliability, and m
