* 7.1 Timer
* 7.3 Speaker
본문내용
- Because of the limited time, we didn`t do changing experiment(R and C). So I`ll just show PSPICE simulation result. We already know that . Above picture follows that when capacitor bigger, waveform`s period become longer. Below picture follows that when resister and capacitor bigger, waveform`s period become longer than input signal period. In conclusion, the larger capacitor makes higher frequency and the larger register makes higher frequency, too.
* 7.3 Speaker
① What is the reason the speaker output sound changes according to the timer`s output?
- Speaker`s sound volume is related with input signal`s amplitude. and speaker`s tone related with input frequency. Timer`s ability is generating frequency relative with input`s amplitude. So when timer`s output become different, not their sound volume change, but speaker`s tone is change.
