c
cutoff frequency
filtering a type of signal conditioning that allows you to remove unwanted frequency
components from the signal you are trying to measure
FSR full scale range
G
gain the factor by which a signal is amplified, sometimes expressed in decibels
gain accuracy a measure of deviation of the gain of an amplifier from the ideal gain
gain error see gain accuracy
H
hold mode
settling time the time it takes for a sample-and-hold circuit to switch from sampling
(tracking) mode to hold mode and settle within a given percentage at the
true hold value
hold step the difference in the true hold value and the measured hold value in a
sample-and-hold circuit
Hz hertz—cycles per second of a periodic signal

in. inch or inches
input bias current the current that flows into the inputs of a circuit
input impedance the measured resistance and capacitance between the input terminals of a
circuit
