The fundamentalfrequency and the harmonics together form aFourier series of the original waveform.High-level data link control. The internationalstandard communication protocol defined by ISO.A base 16 number system commonly used withpersonal computers.See HPFA graphic representation of a distributionfunction, such as frequency, by means ofrectangles whose widths represent the intervalsinto which the range of observed values is dividedand whose heights represent the number ofobservations occurring in each interval.High pass filter. A filter processing onetransmission band that extends from a cutofffrequency (other than zero) to infinity.Hewlett-Packard Interface Bus; trade name usedby Hewlett-Packard for its implementation of theIEEE 488 standard.A method that allows the CPU to distinguishbetween different boards in a system. All boardsmust have different addresses.Institute of Electrical and Electronic Engineers. AUS-based international professional society thatissues its own standards and, which is a memberof ANSI and ISO.An amount of source light incident on the objectbeing viewed.Input look-up table.A system allowing an individual gain level foreach input channel, thereby allowing a muchwider range of input levels and types withoutsacrificing accuracy on low-level signals.A shared boundary defined by common physicalinterconnection characteristics, signalcharacteristics, and measuring of interchangedsignals.This is the display of two fields alternately withone field filling in the blank lines of the other field
