PPT-TRANSISTOR TUNED AMPLIFIERS

  Inroduction Sometimes it is desired that an amplifier should amplify either a single frequency or a narrow band of frequencies For instance radio and television transmission are carried on specific radio frequency assigned to the broadcasting stations . The best bipolar amplifiers offe r offset voltages of 25 V and 01 VC drift Offset voltages less than 5 V with practically no measurable offset drift are obtainable with choppers albeit with some penalties A basic chopper amplifier circuit is shown i 1 Fall 1999 Transistor Amplifiers Purpose The aim of this experiment is to develop a bipolar transistor amplifier with a voltage gain of minus 25 The amplifier must accept input signals from a source impedance of 1 k and provide an undistorted output FROM RESEARCH TO PUBLICATION.

A transistor amplifier that raises the power level of the signals that have audio range is known as transistor audio power amplifier. In general, the last stage of a multistage amplifier the power stage. The power amplifier differs from all the previous stages in that here a concentrated effort is made to obtain maximum output power. A transistor that is suitable for power amplification is generally called a power transistor. It differs from other transistors mostly in size; it is considerably larger to provide for handling the great amount of power.. A Veprik, a TUITTO. Scd. , . imod. OUTLINE.
