1. The problem statement, all variables and given/known data -Find The DC voltage of the signal below created by the function generator -Find RMS Voltage -if the V waveform is applied across 1000 Ohm load what is the power dissipated in the load? http://www.imagedump.com/index.cgi?pick=get&tp=515966 The wave form has axis symmetry which means only cosine terms 2. Relevant equations If the signal was a unit step function only all I would need is the average value to determine the DC component. How do I get that value of a Unit Ramp Function? Would it be an RMS value? If so does Vrms=Vp/sqrt(2)? Since there are several numbers of different wave forms would I get the DC component by using Fourier Series? 3. The attempt at a solution Fourier Series: The wave form has axis symmetry which means only cosine terms The area on the top side is smaller than the area on the bottom side so the DC component will be negative. If it was a pulse, the average voltage would be, Vav=(duty cycle)(peak value)+(1-duty cycle)(Vb) If it was a sin it would be Vrms=Vp/sqrt(2) Im not sure what the average voltage of a ramp wave is! Im gonna guess, a0 = 1/T0* int(f(t)dt, t,-T0/2, +T0/2) But I cant figure out how to apply it!
