In an analogue computer,

AInput is first converted to digital form

BInput is never converted to digital form ✓ Correct

COutput is displayed in digital form

DAll of the above

Correct answer: (B) Input is never converted to digital form

Explanation

In an analogue computer the input is never converted to digital form and is used as continuous signals.

Converting the input first to digital form describes a digital computer, not an analogue one.

Displaying the output in digital form again fits a digital machine.

The all-of-these choice cannot hold, since the other claims are wrong.

Analogue computers work with continuously varying quantities such as voltage or pressure.

They were once used for simulations before digital machines replaced them.
