a unity gain non inverting amplifier. Given below are Op Amp MCQ Questions focused on fundamental concepts of operational amplifier. If desired, a SPDT switch may be used to allow the amp to be switched from bridge back to normal mode. Each question carries 1 point. The energy required by the amplifier to amplify the distorted signal is transferred to it by the DC power source..

The figure below shows a widely used type of Wien bridge oscillator. C. a comparator with three trigger points. This is a very common wiring use of a 4 channel amp for situations in which you’d like more power available and don’t need 4 separate amplifier channels. Be aware of the fact that if your amplifier is a stereo amplifier (amplifying both left and right), bridging it would cause it to become a mono amplifier (amplifying from one; either the left or right). b) a monostable multivibrator MCQ Topic Outline included in ECE Board Exam Syllabi . If an inductance is connected in one arm of bridge and resistances in the remaining three arms (a) the bridge … In this section of Electronic Devices and Circuits.It contain Operational Amplifiers (OP AMPS) MCQs (Multiple Choice Questions Answers).All the MCQs (Multiple Choice Question Answers) requires in depth reading of Electronic Devices and Circuits Subject as the hardness level of MCQs have been kept to advance level.These Sets of Questions are very helpful in Preparing for various Competitive Exams … Operational amplifiers were originally used to perform the mathematical operations such as addition, subtraction, integration, and division (thus the name operational is given). No negative points for wrong answers.
