QUESTION 3 5pts If vi(t) = -10 sin(wt - 30°) V and vz(t) = 20 cos(wt +45°) V. find v(t) = V(t) + vz(t)
In Problems 4.1 to 4.6, the input voltage V, is dc and positive with Switch 4 the polarity shown. Specify how to implement the switches using a position minimal number of diodes and transistors, such that the converter operates over the entire range of duty cycles OSDS 1. The switch states should vary as shown in Fig. 4.56. You may assume that the inductor current ripples and capacitor voltage ripples are small. For each problem, do the following: DTT, (a)...
Learning Goal: To use the mesh-current method to analyze circuits containing resistors and independent voltage sources. The mesh-current method is a general technique for solving circuits. Fundamentally, it involves writing KVL equations around all meshes in a circuit. You should review KVL and the definition of a mesh before beginning. In this tutorial, you will use the mesh- current method to find the current through the 1 k2 resistor, io, and the voltage drop across the 5 k22 resistor, vo,...

Please use MATLAB for the specified parts, I appreciate the help! 1. Complex Numbers and phasor analysis can be used to solve many problems. For example if we want to determine the currents of each of the voltage sources in the following circuit, VI ov then we can use a technique called mesh analysis to write mesh equations that involve the currents of each source. Let libe the current of the voltage source vl = 2 cos(t), I be the...
