Answer 2

Analog computers use linear combinations of voltage amplitude (or currents or frequencies or phases) instead of digits.  

Explanation:

An analog computer are early computer devices that used continuously changeable aspects of physical phenomena to model the problem that is being solved. It can use either electrical, mechanical, or hydraulic quantities.

Analog computers involve a wide range of complexity.  They were used in scientific and industrial applications because they were fast. This made them stand even after the invention of digital computers, but slowly became obsolete in 1950s and 1960s.
