Hi I'm a yr 12 student and currently doing a physics assignment; we constructed a oscillator circuit to make an LED flash and we had to control the flashing frequency. Pretty standard, but my problem is with the graphs I obtained. We used the program Audacity to graph the output, I expected a square wave, but some other thing came out - looks kind of like the charge discharge cycles of the capacitor except when it is charging (ON), it is the discharge curve and vice versa for the off cycle. What type of wave is this and why is it being generated?
Thank you!
Thank you!
