In the campus placement season, it is better if we get company specific questions to prepare for the selection process. So, to help you out, we have already posted Question Banks for some core ECE companies and now, let us look at the following questions asked in recent times in Qualcomm interviews. In general, according…
Bharat Electronics Limited (BEL) Question Bank continued from Part 3… Q-20. State a way to improve SNR at the input of an amplifier. A : Signal to Noise Ratio (SNR) at the input of an amplifier can be improved by decreasing the source impedance (or resistance). Q-21. Why are N channel FETs superior to P channel…
