EE315A Spring 2009 B. Murmann Page 1 of 2 Last modified 4/12/09 6:51 PM HOMEWORK #2 (Due: Thursday, April 16, 2009, 1pm PT) 1. Design a 4 th order Butterworth lowpass filter with 0.3 dB maximum attenuation (worst case) in the passband (0 Hz to 500 kHz) and a nominal gain of 1. Implement the design using two Sallen-Key sections. The available resistors exhibit worst-case variations of ± 15%, capacitors vary by ± 10%. The resistors and capacitors, respectively, vary by the same percentage. E.g. if R 1 increases by 5% from 1 k Ω to 1.05 k Ω , all other resistors increase also by 5%. Likewise, all capacitors change by equal percentages. Note, however, that the resistor and capacitor variations are uncorrelated, i.e. they usually change by different percentages. This is typical for components fabricated on an integrated circuit. In your design, the (nominal) resistor values must be no larger than 100 k Ω and the capacitor values should be minimized. Set G=1 for both stages.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
