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
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
alias a false lower frequency component that appears in sampled data acquired
at too low a sampling rate
amplification a type of signal conditioning that improves accuracy in the resulting
digitized signal and reduces noise
amplitude flatness a measure of how close to constant thegain of a circuit remains over arange
of frequencies
analog bandwidth the frequency at which the measured amplitude is 3 dB below the actual
amplitude of the signal. This amplitude loss occurs at very low frequencies
if the signal is AC coupled and at very high frequencies, regardless
of coupling
Analog Trigger
Circuit Output
digital output of the analog trigger circuit
ANSI American National Standards Institute
ASIC Application-Specific Integrated Circuit—a proprietary semiconductor
component designed and manufactured to perform a set of specific
functions for a specific customer
attenuate to decrease the amplitude of a signal
attenuation ratio the factor by which a signal’s amplitude is decreased
B
bbit—one binary digit, either 0 or 1
Bbyte—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
