⑵ Audio amplifier
Audio amplifier also make improper signal. First, we implemented the audio amplifier circuit without checking the operation. Then it didn`t work. We only heard noise. So we implemented it another position again. But it also didn`t work. So we supplied the Vcc with DC voltage source to operate single opamp. In other words, we observe signal through using DC source directly. At that time, we heard not only lot`s of noises but also faint sounds. We can`t obtain clear signal and we can`t amplify signal. On the contrary, signal somewhat decrease. Consequently we can`t obtain experiment result. So we think about reason of failure. First thing is organizing circuit improperly. This circuit have lots of elements and each opamp requires lots of connecting points. So we somewhat confuse. Actually, when we connect the male and female headphone jack we connect wrong position.
