2. Design and Build of Transistor Circuit for Industrial Applications 2.1 Class A Power Amplifier: The circuit Figure 7 illustrates Class A common- emitter power amplifier and is recommended for conducting

an analysis of the amplifier. [For maximum output signal, the Q-point must be centered where a non-centered Q-point limits the output swing] Experiments: Verify the parameters being measured by the various Multimeter. (What are they? What are their clues/evidence/explanation?) . • Calculate the maximum AC output current and DC input power using the formulas given by: V = max collector-to-emitter voltage swing. I = max collector current swing. . Calculate the efficiency and discuss the result from a Class A amplifier. Report your findings.
