GATE Measurements and Control Systems: Measurement Errors and Uncertainty – Previous Year Questions
6 GATE previous year questions on Measurement Errors and Uncertainty (Measurements and Control Systems, Biomedical Engineering) with answers and explanations, from every paper.
- GATE 2021 BM Q45 – An ideal 5 V source drives two series 100 Ω resistors, and voltmeters V1,V2 measure the drop across one. At five times, V1 readings are…
- GATE 2022 BM Q58 – Three independent sensor measurements (mean ± standard deviation) are 4.52±0.02 V, 4.21±0.20 V and 3.96±0.15 V. Find uncertainty of their sum in V to…
- GATE 2023 BM Q37 – A 20 mV DC signal is superimposed with 10 mV RMS Gaussian noise whose spectrum is flat up to 5 kHz. An integrating voltmeter measures the DC signal.…
- GATE 2024 BM Q32 – Measured current is 5 A and voltage 20 V. Each instrument has 1% uncertainty. Find maximum first-order error in the estimated impedance, nearest…
- GATE 2025 BM Q35 – A test EEG device measures 2.4 μV while a reference measures 3.0 μV. Find the magnitude of percentage error of the test device.
- GATE 2026 BM Q56 – Resistance is 60±2 Ω and measured voltage across it is 120±10 mV. Estimate uncertainty of dissipated power in mW, rounded to one decimal place.
