Answer: Option A
Answer: (a)
An Analog computer works on the supply of Continuous electrical pulses.
An Analog computer works by measuring voltages and currents rather than by the process of counting. An Analog computer works on the supply of continuous electrical signals and displays output continuously. Side rule is an example Analog device in which numbers as expressed as distances.
A computer that operates with numbers represented by directly measurable quantities (such as voltages or rotations) — compare to a digital computer, a hybrid computer. This contrasts with an Analog signal, which represents continuous values; at any given time it represents a real number within a continuous range of values.
