Question

Consider the resonant filter shown below. The source voltage Vin is a square-wave voltage with 2. frequency 60 Hz, similar to what would be produced by a full-bridge inverter. out a. Find an expression for the transfer function us) of ths fiter. a. Find an expression for the transfer function ot (j) of this filter. The load resistance is 100 Ω. Find the values of L and C to satisfy these two conditions: b. The filter attenuation factor at the fundamental frequency should be 1. . The filter attenuation factor at the third harmonic frequency should be 10 For the values calculated in (b), find the attenuation of the fifth harmonic. c.
