ACcoupled allowingthe transmission of AC signals while blocking DC signals
ADC analog-to-digital converter—anelectronic device, often an integrated
circuit, that convertsan analog voltage to a digital number
ADC resolution theresolution of the ADC, which is measured in b its. An ADC with 16 bits
has a higher resolution, and thus a higher degree of accuracy,than a
12-bitA DC
alias afalse lower frequency component that appears in sampled data acquired
at too lowa sampling rate
amplification atype of signal conditioning that improves accuracy in the resulting
digitized signal and reduces noise
amplitude flatness ameasure of how close to constant the gain of a circuit remains over a range
offrequ encies
analog bandwidth the frequency at which the measured amplitude is 3 dB below the actual
amplitudeof the signal. This amplitude lo sso ccurs at veryl owfrequencies
ifthe signal is AC coupled and at very high frequencies, regardless
ofco upling
Analog Trigger
Circuit Output
digital output of the analog trigger circuit

attenuate todecrease the amplitude of a signal
attenuation ratio thefactor bywhich 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
