1.	Which operation class is generally used in radio or communications?(a) A(b) B(c) C(d) DThe question was posed to me in a national level competition.The doubt is from Classification of Output Stages in portion Differential and Multistage Amplifiers of Electronic Devices & Circuits
Answer» Correct option is (c) C To explain: In radio or COMMUNICATIONS, generally class C is used in case of HIGH level modulation.High level modulation uses class C amplifiers in a broadcast AM TRANSMITTER and only the final stage or final two stages are modulated, and all the EARLIER stages can be driven at a constant level.
