Unformatted text preview: result to find i. Read and perform the examples in PSPICE Tutorial #5 before attempting problems 8 – 9. For both problems turn in the PSPICE schematic and a plot of the circuit output as specified. 8. Use PSPICE to simulate the circuit in problem 5. Apply a 0.1 volt, 1KHz sinusoidal signal as the input. Use R 1 = 1K Ω , R 2 = 4K Ω , R 3 = 2K Ω , and R 4 = 8K Ω . Measure the circuit output voltage V o . Use DC supplies of +/- 15 volts. 9. Use PSPICE to simulate the circuit in problem 6 and find the output current, i. Use DC supplies of +/- 25 volts....
