Tuned Amplifier Question & Answers September 26, 2022 By WatElectronics This article lists 40 Tuned Amplifier MCQs for engineering students. All the Tuned Amplifier Questions & Answers given below include a hint and a link wherever possible to the relevant topic. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up on the fundamentals of a Tuned Amplifier. An amplifier is a device used for amplifying the strength of a signal. It comprises of 2 ports and is classified into 2 types large signal tuned amplifier and a small signal tuned amplifier. Small signal tuned amplifiers are classified as single tuned amplifiers, double tuned amplifiers, and multiple tuned amplifiers. A tuned type of amplifier considers certain frequencies and rejects certain frequencies. A tuned amplifier tunes both radio and higher frequencies. It comprises of passive components such as RLC, and the frequency of the circuit is given as F=1/2Pi[sqrt LC]. LC is a combination of tuned amplifiers. At low bandwidth, the single-tuned amplifier cannot amplify. An amplifier with multiple stages tuned amplifier is a staggered tuned amplifier. The advantages of a tuned amplifier include good SNR, greater selectivity, and low power loss. The disadvantages of single-tuned type amplifiers include high bandwidth. The applications of tuned amplifiers include TV, radio, and wireless communications. 1). Tuned amplifier is _____ type of amplifier? Electronic Mechanical Electrical Both a and b Hint 2).
