Question continued. b) Before inserting the filter circuit between the wind turbine and phone charger you have decided to test its performance using a variable frequency signal generator and a resistive load, as shown in Figure Q4-2. i) You have determined that the first two undesirable harmonics can be expressed as: vi(t)=0.7cos(80x1) and va(t)= 3.3cos(120xt). Determine the voltage across the load resistor shown in Figure Q4-2 when the signal generator is configured to produce an output of vi(t) and v₂(1). 1 ii) State one way in which the performance of your filter could be improved.
