Objectives of this experiment:To construct a complementary transistor power amplifier.
To measure two different types of distortion (cross-over distortion & distortion due to nonlinearly) by observing it on an oscilloscope, or hearing from a loud speaker. On a CRO, you can observe the different output waveforms produced, while the circuit bias is changed and while the input signal level is changed. You can also hear two different types of distortion from a loudspeaker.
