Question

Easy circuits problem.

Design and simulate each of the cases:

In this lab you must design a ferrite-core transformer to illustrate the concepts oif mutual coupling and the impedance matching You w be provided with a ferrite core and copper wire to construct a transformer with desired primary, and secondary windings. Your instructor will give you more details on the physical construction of this transformer. Since the signal generators in our lab have an inherent input impedance of 50 ohms, you can assume you will have a circuit similar to the one given below in figure 1: R2 0 V1 50 AC1L1 L2 0 K1 L1 L21 Figure 1- LTSpice simulation of transformer For the experiments in this lab, we will use a frequency of 1MHz from the signal generator. (1)With the signal generator set to 10 V amplitude, design a transformer circuit with a turns ratio that will give a 5V amplitude signal at the output with no load (open circuit on the secondary winding) Design a transformer to match a 25Ω load resistor (not shown in figure 1) to the 50Ω source resistance of the signal generator. Determine the maximum power transferred when the signal generator is set to an amplitude of 10V (2)

Ltspice and explanation will be helpful. Thanks
