Hi. Iamp;#39;m Travis, and Iamp;#39;m an engineer on the academic team here at National Instruments. And today I want to show you a new approach to teaching frequency response calculations of filtering circuits. As you know, active filters are very common building blocks of electronic circuits. When a student is introduced to the concept for the very first time, a single low pass op-amp filter, such as the one shown here, is a good example to explain the circuit theory and how to mathematically calculate the cutoff frequency. However, when circuit complexity increases, such as in the case of this third order low pass filter, the theory becomes much more challenging. In this new approach, we can start in the same place is traditional coursework by using an exercise in a popular textbook to theoretically calculate the frequency response of a cascaded filter. But I wonamp;#39;t stop there. Iamp;#39;ll then force that theory with SPICE simulation and lab exercise. So now Iamp;#39;m go
