Question

Procedure 1) Based on the BW specified by your TA, build highpass and lowpass 1 order Op Amp Filter circuits. Using sine wave inputs, vary the frequency and observe what happens. Record examples in your notebook that show that these circuits perform the desired operations. Draw the frequency response of the circuits. 2) Using various inputs (square wave, sine wave, etc.), show that the circuits from 1) may also be used for differentiation and integration. Vary the frequency and observe what happens. At some frequency ranges the circuit should not perform the desired mathematical operation. Why? Again record results in your notebook that show the corresponding mathematical operations as well as examples of where the circuit did not work for them. 3) Convert the "almost ideal" Op Amp Differentiator and Integrator circuits to the ideal ones. Test these circuits with various inputs. Again record results in your noteboolk that show the performance of these circuits. Postlab 1) If the same BW is maintained in step 1) of the lab, but the sizes of resistors and 2) If the same BW is maintained in step 2) of the lab, but the sizes of resistors and 3) Explain why the circuits in step 3) of the lab operate as they do. capacitors were varied, how would this affect circuit performance? Compare the prelab and lab frequency responses capacitors were varied, how would this affect circuit performance?

just the postlab and id you need this informarion. but i just. need post lab
