Extracted text: Exercise 1-4: In a certain application, a signal source having 60 k2 of source impedance, Rs. produces a 1-V-ms šignal. This signal must be amplified to 2.5 V mms and drive a 1-k load. Assuming that the phase of the load voltage is of no concem, design an operational amplifier circuit for the application. Hint: Choose, arbitrarily, input resistor, R = 100 kN and find feedback resistor, Rr. Since phase is of no concem and the required voltage gain is greater than 1. we can use eiher an inverting or noninverting anplifier. 12. %3D TAnswers: Rf (imvraing) = 400 k2, R (norimerting)= 150 k2]
