12+ Audio Amplifier Circuit Using Transistors

12+ Audio Amplifier Circuit Using Transistors. But i want to use transistors so i can learn how to use them for amplification. I know there are ic designs specifically for the task.

transistors – Question about bjt audio amplifier circuit … from i.stack.imgur.com

Transistors amplifiers are used frequently in rf (radio frequency), ofc (optic fibre communication), audio amplification, etc. Here we are going to see construction and working of a 2 stage amplifier circuit using transistors. Representing the basic amplifier as a two port network as in figure 9.1.

12+ Audio Amplifier Circuit Using Transistors. Here we used 1943 and 5200 transistor. Similarly audio amplifiers are used to amplify the strength of speech signals and makes it more audible by amplifying it and put it through a speaker. Here we used 1943 and 5200 transistor. The schematic for 10 watt amplifier is pretty simple, the lf351 amplifies the signal voltage and two power transistors provide the necessary power amplification.
