Base on the circuit as show to recreate a real circuit on the bread board.
Using a 2N3904 transistor with resistors and capacitors to create an amplifier.
The two waves on the screen show the voltage supplied by the function generator(top wave) and its output(bottom wave) after amplification of the breadboard circuit. By readying the result on the screen, we can say an amplification emitted about 100 times the original supplied.
Amplifier with Gain = 20 (Minimum Parts)
Base on the this circuit diagram to create an amplifier with a signal semiconductor.
The amplifier that we created on the bread board.
Connecting the amplifier with power supply and speaker to play music from cell phone. After we try to connect to several different speaker, we finally heard the music that playing on my phone from the speaker.
