Fundamental frequencies of square wave and sine wave

[QUOTE="galaxy_twirl, post: 4989231, member: 526444"] Hi gneill. Thank you for your help! :) Ah I see. I determined the f[SUB]0[/SUB] in the lab by feeding in sinusoidal signals, square pulses and triangular waves into the FFT (Fast Fourier Transform) Oscilloscope and they all turned out to match the frequencies supplied by the signal generator regardless of the duty cycle. :) I know from my lecture notes that a sine wave can look like a square wave with squiggles when n becomes a larger number in sin(nx), as seen below: [ATTACH=full]175707[/ATTACH] Do you mean the above in your reply to my question on square wave? :) Just wondering, how do you know how large should the sine wave get into order to achieve a square waveform? Thanks again! :D [/QUOTE]
