AC coupled
allowing the transmission of AC signals while blocking DC signals
ADC
analog-to-digital converter—an electronic device, often an integrated
circuit, that converts an analog voltage to a digital number
circuit, that converts an analog voltage to a digital number
ADC resolution
the resolution of the ADC, which is measured in bits. An ADC with
16 bits has a higher resolution, and thus a higher degree of accuracy,
than a 12-bit ADC.

ADE
application development environment
alias
a false lower frequency component that appears in sampled data acquired
at too low a sampling rate
at too low a sampling rate
amplification
a type of signal conditioning that improves accuracy in the resulting
digitized signal and reduces noise
digitized signal and reduces noise
amplitude flatness
a measure of how close to constant the gain of a circuit remains over a range
of frequencies
of frequencies
analog bandwidth
the range of frequencies to which a measuring device can respond
attenuate
to decrease the amplitude of a signal
B
b
bit—one binary digit, either 0 or 1
B
byte—eight related bits of data, an eight-bit binary number. Also used to
denote the amount of memory required to store one byte of data.

bus
the group of conductors that interconnect individual circuitry in a computer.
Typically, a bus is the expansion vehicle to which I/O or other devices are
connected. An example of the PC bus is the PCI bus.
