engineering recuitment GATE EE 2023-24 Test Series Electrical and Electronics Measurements Digital Voltmeters 3 1/2 Digit DVM
A 3 ½ digit dual slope integrated DVM, 2 V full scale is used to measure a time varying voltage V(t) = 1.0 + 2 sin 50 πt. The voltmeter indicates
1
1.00 V
2
1.732 V
3
2.000 V
4
Wrong value. To show the correct reading we need to increase the range of full scale deflection as the reading will be more than 2 V.
