Question

Accuracy depends on ____________

(a) input voltage

(b) drop across the capacitor

(c) magnitude and stability of pulse generator

(d) magnitude of the ramp

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

The above asked question is from Voltage to Frequency Converter Type Integrating DVM in portion Electronic Instruments of Electrical Measurements

Answer 1

Correct choice is (c) magnitude and stability of pulse generator

Explanation: Accuracy of the voltage to frequency conversion depends on the capacity of the pulse generator to produce an electric charge with a suitable magnitude and stability. Hence the accuracy depends on the precision of the charge feedback.
