1.31 Using the information provided by Eq. (1.2) in association with Fig. 1.5, characterize the signal represented by v(t) = 1/2 + 2/π(sin2000πt + 1 3 sin6000πt + 1 5 sin10,000πt + ···). Sketch the waveform. What is its average value? Its peak-to-peak value? Its lowest value? Its highest value? Its frequency? Its period?
