Question

Linear ramp technique is based on __________

(a) voltage measurement

(b) time measurement

(c) current measurement

(d) resistance measurement

I had been asked this question by my school principal while I was bunking the class.

I'm obligated to ask this question of Ramp Type DVM in division Electronic Instruments of Electrical Measurements

Answer 1

Right answer is (b) time measurement

To explain I would say: Linear ramp technique works on the principle of measurement of time required by a linear ramp to rise from 0 V to the input voltage. It can also be the time required by the input voltage to fall to 0 V.
