Electric Circuits, 9th Edition P63. 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. | 596 Active Filter Circuits a Using only three components from Appendix H design a low-pass filter with a cutoff frequency and passband gain as close as possible to the specifications in Problem a . Draw the circuit diagram and label all component values. b Calculate the percent error in this new filter s cutoff frequency and passband gain when compared to the values specified in Problem a . Design an op amp-based high-pass filter with a cutoff frequency of 4 kHz and a passband gain of 8 using a 250 nF capacitor. a Draw your circuit labeling the component values and the output voltage. b If the value of the feedback resistor in the filter is changed but the value of the resistor in the forward path is unchanged what characteristic of the filter is changed The input to the high-pass filter designed in Problem is 250 cos mV. a Suppose the power supplies are Vrt. What is the smallest value of Vcc that will still cause the op amp to operate in its linear region b Find the output voltage when oc. c Find the output voltage when w . d Find the output voltage when w 5io0. a Use the circuit in Fig. to design a high-pass design filter with a cutoff frequency of 8 kHz and a passband gain of 14 dB. Use a nF capacitor in the design. b Draw the circuit diagram of the filter and label all the components. Using only three components from Appendix H design a high-pass filter with a cutoff frequency and passband gain as close as possible to the specifications in Problem . a Draw the circuit diagram and label all component values. b Calculate the percent error in this new filter s cutoff frequency and passband gain when compared to the values specified in Problem a . Section The voltage transfer function for either high-pass prototype filter shown in Fig. is Figure The voltage transfer function of either low-pass prototype filter shown in Fig. is W t- 7 5 1 Show that if either .
