analog input channel signal
analog-to-digital
analog-to-digital converter—an electronic device, often an integrated
circuit, that converts an analog voltage to a digital number
a false lower frequency component that appears in sampled data acquired
at too low a sampling rate
a type of signal conditioning that improves accuracy in the resulting
digitized signal and reduces noise
a measure of how close to constant the gain of a circuit remains over a range
of frequencies
analog output ground signal
to decrease the amplitude of a signal
the factor by which a signal's amplitude is decreased
bit—one binary digit, either 0 or 1
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.
the range of frequencies present in a signal, or the range of frequencies to
which a measuring device can respond
a signal range that includes both positive and negative values (for example,
–5 V to +5 V)
a type of coaxial signal connector
