Question

Which is the main device used in the linear ramp technique?

(a) exponential ramp

(b) asymptotic ramp

(c) non-linear ramp

(d) linear ramp

I have been asked this question during an interview for a job.

The above asked question is from Ramp Type DVM topic in section Electronic Instruments of Electrical Measurements

Answer 1

Right answer is (d) linear ramp

To elaborate: The linear ramp technique essentially consists of a linear ramp. It is either positive or negative going. Range of the linear ramp varies from –12 V to +12 V. Base range varies from –10 V to +10 V.
