Signals and Networks • (SEE 2043) • Lecture #19 • Topics covered • Exercises -Bode Plot for Filters
Next Task…. • We have: • Understand the Bode Plot (real poles and zeros, complex poles and zeros) • Understand the filter type (LPF, HPF and BPF) and order of the filter. Our task now is to: • Obtain the transfer function from the given electrical circuit and determine the filter type based on the sketched Bode Plot. • Obtain the Bode Plot of the given transfer function and determine the filter type
