Analog Technology
  • A form of measurement or representation in which an indicator is varied continuously, often reflect ongoing changes in the phenomenon being measured or represented. Analog representation is used, for example, in a thermometer: the hotter the patient, the longer the mercury. Analog techniques also are used for the reproduction of music in standard Lp records and audio cassettes. A computer that draws a comparison, or analogy, between the computer representation and the object being represented, making the object easy to measure. Analog computation is used widely in laboratory settings to monitor on-going, continuous changes and record these changes in charts or graphs. (QCUS+Pf-90
