We have yet to be formally taught the Fourier transform, but an Amplitude spectrum is a plot of amplitude vs frequency and a phase spectrum is a plot of phase shift vs frequency.

The problem statement Sketch the Amp spectrum of the following... Additionally, for x3, sketch the phase spectrum... ( j is the imaginary number) x1(t) = cos(10pi*t) + cos(3pi*t) x2(t) = cos(10pi*t) + cos(5pi*t) - j*sin(10pi*t) x3(t) = cos(10pi*t + (pi/6)) + j*sin(10pi*t) The...

The problem statement 7. In the circuit below, the resistor R3 models a light bulb. a) Use superposition to find iX. b) Find the Norton equivalent as seen by the independent current source, iS2. c) Find the power delivered by the independent current source, iS2, in the circuit below. Diagram...

Forgive the title, I was unsure of how to briefly describe the problem. Attached are diagrams. Homework Statement The device shown in Figure P2.5 can be modeled as a current source in parallel with a resistance. When this device is connected to a 5[mA] current source, so that...
