The voltage source in Figure 8–37 produces a 60-Hz sinusoid with a peak amplitude of 200 V plus a 180-Hz third harmonic with a peak amplitude of 10 V, that is, υSðtÞ = 200 cos ð2π 60tÞ + 10 cos ð2π 180tÞ V. The purpose of the LC T-circuit is to reduce the relative size of the third-harmonic component delivered to the 100-Ω

load resistor. Use MATLAB to calculate the voltage amplitudes across the load caused by the 60-Hz and the 180-Hz signals. For each frequency, determine the magnitude of the ratio of the output voltage to the input voltage. Is the circuit performing its task?
