E
EEPROM electrically erasable programmable read-only memory—ROM that can be
erased with an electrical signal and reprogrammed
equivalent time
sampling
any method used to sample signals in such a way that the apparent sampling
rate is higher than the real sampling rate
event the condition or state of an analog or digital signal
F
filtering a type of signal conditioning that allows you to filter unwanted signals from
the signal you are trying to measure
fs full-scale—total voltage in the input range. A ±10 V input range is 20 V fs
G
gain the factor by which a signal is amplified, sometimes expressed in decibels
H
hardware the physical components of a computer system, such as the circuit boards,
plug-in boards, chassis, enclosures, peripherals, cables, and so on
harmonics multiples of the fundamental frequency of a signal
Hz hertz—per second, as in cycles per second or samples per second
I
I/O input/output—the transfer of data to/from a computer system involving
communications channels, operator interface devices, and/or data
acquisition and control interfaces
inductance the relationship of induced voltage to current
input bias current the current that flows into the inputs of a circuit
