tailieunhanh - Electric Circuits, 9th Edition P71

Electric Circuits, 9th Edition P71. Designed for use in a one or two-semester Introductory Circuit Analysis or Circuit Theory Course taught in Electrical or Computer Engineering Departments. Electric Circuits 9/e is the most widely used introductory circuits textbook of the past 25 years. As this book has evolved over the years to meet the changing learning styles of students, importantly, the underlying teaching approaches and philosophies remain unchanged. | 676 The Fourier Transform Figure 10 fl ---------W- 1 H What percentage of the total 1 fl energy content in the output current i0 lies in the frequency range 0 co 100 rad s Figure 500 mH a Use the Fourier transform method to find vo in pspice the circuit in Fig. when MULTISIM ig 18el M-f - 18e- i zi t A. b Find t 0 . c Find wo 0 . d Do the answers obtained in b and c make sense in terms of known circuit behavior Explain.
