    Engineering Solving a circuit in Freq Domain

    Do you know the equation? I was getting an amplitude of about 6, not sure how to extract the phase shift from the plot.

    Engineering Solving a circuit in Freq Domain

    He specifically said that the (+) is on top. And when I worked it out by hand following his steps, I got what seems to be an appropriate answer.

    Engineering Solving a circuit in Freq Domain

    Are you 100% positive it does not reach steady state? Cause everything we have done in class has been for steady state problems. I find it hard to believe he is giving us a problem that we have never seen before.

    Engineering BJT Transistor for Motor Control - PIC Microcontroller Interface

    Homework Statement You want to use a PIC microcontroller to drive a motor in a clockwise direction at either 0% speed (when the PIC output is 0V) or full speed (when the PIC output is +5V). This motor draws 500mA at +5V while the output of the used PIC is limited to +5V and 20mA. To solve...

    How do I find Fourier series coefficients for triangular and sawtooth waveforms?

    Triangular and sawtooth waveforms. I solved for the coeffiecients for the square wave, and was wondering if you do the same for triangular and sawtooth. I keep getting large/messy integrals that do not seem to simplify. The thing that is messing me up is that the waveform is linear with a...
