Ok so I have this question where I'm asked to draw the frequency spectrum of a square wave:
**broken link removed**
then I went ahead and looked at the answer which was :
**broken link removed**
So I have no idea how they got this answers,but I'm guessing that for the magnitudes they are just V/1,V/3,V/5,V/7,V/9 ... (V=voltage of square wave) and for the frequencies they are just f*1,f*3,f*5,f*7,f*9...(f=frequency of square wave) ,and that we use 1,3,5,7,9 because a square wave only contains odd harmonics.Am I correct?I'm quite unsure about this.
Thanks in advance!
