Hi all,I don't know if it's the right place for this question but I hope you can help me :)

for the waveform in the picture f(t):




1-determine the mean square value in the time domain
2-find the PSD (assume 1 ohm) and sketch it.

Sorry for not reading the rules before starting new thread, the problem is I don't know what is
f(t) here , I don't think it's cosine because no -1, what f(t) could be?
