hi there I conducted the Fourier series to genrate sawtooth

hi there,

I conducted the Fourier series to genrate sawtooth , I used three function generators to get three peaks in sawtooth on an oscilloscope. but I got two peaks in sawtooth .

Why that happen? if you know the reason please let me know.

thank you

Solution

Check the time axis it should be more than three times the period of sawtooth wave...it may work...
