Electronics Engineering MCQ Questions Answers (ECE) Subject Wise Material & Compound Physical Electronics & Devices Signals & Systems Electromagnetic Theory Measurements & Instrumentation Network Theory Communication Systems Microwave Engineering Alternating Currents Analog Electronic Circuits Digital Electronic Circuits 1.The impedance curve of an R-L-C network cuts the frequency axis only when the frequency is such that (a) reduce to half (b) double too 6. (a) Hartley oscillator (b) collpitt oscillator I found these questions very helpful. But as a fresher HR round plays a crucial role in the interview. During your teaching interview, you'll need to do more than just give generic responses to the questions you're asked. (a) 3 (b) ½ (a) the output of phase comparator (b) the output of low pass filter Demodulation is the act of removing the modulation from an analog signal to get the original baseband signal back. (c) wein-bridge oscillator (d) R-C phase shift oscillator. The basic difference lies in the Multiplexing method used in the aerial communication i.e. 3. the junction diode’s capacitance that is made use of in varactors is known as (b) electromagnetic means Also, I want to know; can I get subject wise questions and answers? Each base station can only cope with a certain number of calls at any one time. 14. What Is Diode? What is multiplexing? Employers will be interested in how you’ve conquered challenges in the past, whether you’ll fit into their corporate culture. Radio communication superimposes this information bearing signal onto a carrier signal. So if demand exceeds the capacity of a base station an additional base station is needed. Each cellular Base Station is allocated a group of … 7. (c) E,F1,F2 layers (d) E and F2 layers. The Microcell is used to improve capacity in areas where demand to make calls is high, such as shopping centres.
