EE 205 Dr. A. Zidouri-2-The material to be covered in this lecture is as follows: oIntroduction to the Low Pass filter oThe Series RL Circuit- Qualitative Analysis oDefining The Cutoff Frequency oThe Series RL Circuit- Quantitative Analysis After finishing this lecture you should be able to: ¾Understand the Behavior of Low-Pass Filters ¾Understand the cutoff frequency. ¾Relate cutoff frequency to component values ¾Analyze Qualitatively And Quantitatively A Low-Pass Filter ¾Design A Simple Low-Pass Filter
EE 205 Dr. A. Zidouri-3-Introduction to Low Pass Filter Filters that will be considered here and in following lectures are passive filters. We will examine in this and next lecture two circuits that behave as low-pass filters Fig. 36-1 oSeries RL Circuit oSeries RC Circuit Discover what characteristics of these circuits determine the cutoff frequency. Note across which element the output signal is taken for the above two circuits
