EECS 314 Winter 2010 Homework 2 Required reading for Problem 2 © 2010 Alexander Ganago Page 1 of 4 File: Saw‐tooth harmonics The Saw‐Tooth Waveform and Its Harmonic Components The saw‐tooth waveform (also called the ramp ) represents the voltage V(t) that linearly increases as function of time from its minimal value V min to its maximal value V max , and abruptly drops from V max to V min , as shown in Figure 1. Figure 1. The saw‐tooth waveform: voltage as function of time. The difference between the maximal and the minimal voltages is called the peak-to- peak amplitude, which equals twice the peak amplitude of the waveform: V max V min = V peak to peak = 2 V peak [equation 1] The Rise Time is defined as the time interval between the moment when the voltage rises above the low level that equals V min + 0.1 V peak to peak [equation 2] and the moment when it reaches the high level equal to V min + 0.9 V peak to peak [equation 3] Due to the linear increase of the voltage V(t), the Rise Time for a saw‐tooth waveform is easy to calculate algebraically. The Fall Time, which is defined accordingly, equals zero for a perfect saw‐tooth.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
