, Analog Quantities
• An analog quantity is one having continuous values. For
example:
– Intensity of light
– Temperature
– Velocity
, Digital Quantities
• A digital Quantity is one having a discrete set of values.
– Digital data can be processed and transmitted more
efficiently and reliably than analog data.
– Digital data has a great advantage when storage is
necessary.
