Unformatted text preview: Part B. In Part B we examine a push-pull circuit set up as shown below. In a) will dont wire up the speaker, but instead focus on the output and how it changes from the input. In b) we compare the sound emitted from a speaker hooked up directly to the function generator to the sound of a speaker hooked up to the output of our push-pull. Data a) b) the sounds gets louder but with beating Part B Conclusion When we looked at the output in a) we saw that the output goes to zero and stays at zero for a short period of time instead of curving smoothly across it. This is because if V V in 6 . 6 . -then neither transistor emits anything. In b) the sound is amplified because the pnp amplifies negative voltages while the npn amplifies positive ones but there is beating because of the cross-over distortion....
