UGC NET Electronic Science case studies
UGC NET Electronic Science · Put your knowledge to work in context.
UGC-NET (UGC National Eligibility Test) is a national-level eligibility examination administered by the National Testing Agency (NTA) for candidates seeking eligibility for Assistant Professor and/or Junior Research Fellowship (JRF) in Indian universities and colleges. The Electronic Science subject paper is one of the 84 subjects offered in the June 2026 cycle, as indicated by the NTA notice on category-wise cut-off marks. The UGC NET Electronic Science case studies are 5 cases and about 3,692 words.
1Thermocouple front end that saturates and picks up heater noise
A furnace monitoring channel uses a Type-K thermocouple with a Seebeck coefficient of about 41 µV/°C and a cold-junction compensator. The intended range is 0–600 °C, so the full-scale thermocouple voltage is about 24.6 mV.

A DSP block in a 28 nm ASIC runs at 125 MHz, giving an 8 ns period. The critical path is the multiply-accumulate loop of a first-order IIR filter, y[n] = a·y[n−1] + b·x[n].

An isolated telecom converter steps 48 V nominal (36–60 V) down to 12 V at 5 A using a synchronous buck at 200 kHz. The chosen inductor is 22 µH with 6.0 A saturation and 30 mΩ DCR; the output capacitor is 100 µF with 20 mΩ ESR.
