∙Power Supply for an Audio Amplifier
① Record the data and answer to the questions according to each step.
1. The Transformer
- Graph Vout using oscilloscope(Check Max, Min )
- Record Max/Min value of Vout.
→ Max : 19v, Min : -19v
- Observe that Vout is not an exact sinusoidal wave, and think of the reason.
→ By observing the oscilloscope screen we can easily find out the distortion of the wave. The distortion of the wave happens because of increasing the loss of condenser. The high temperature also can be the reason of the distortion, we can observe the voltage fluctuation from the wave. These reasons couldn`t make the wave exact form of sinusoidal wave. Otherwise it might be influenced by signal noise, voltage dropping.
- Measure the frequency of Vout, and analyze the reason.
→ The frequency of Vout is 60Hz. The transformer doesn`t affect the frequency of signal even though it affects the alteration of voltage.
