Qualcomm Interview Question Bank continued from Part 2… Q : What is the difference between latch and flip-flop? A : The main differences between latch and flip-flop can be understood here. Q : What is the Nyquist rate condition and condition for no aliasing to take place? A : If a signal is bandlimited to W…
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 4… Q-29. If the gain of the amplifier is A and voltage feedback is fraction B of the amplifier output voltage, what will be the condition for maintenance of oscillation? A : The condition for maintenance of oscillation would be AB = 1. Q-30. State the condition…
