Frequency Response: Descriptors and Bode Diagrams

This lecture covers the frequency-response descriptors and Bode diagrams, explaining the first-order low-pass and high-pass responses, bandpass and bandstop responses, and the frequency response of RLC circuits. It delves into the historical significance of Hendrik Bode's contributions to feedback amplifier theory and the industry-standard Bode plots. The lecture also discusses the importance of using network functions and Bode diagrams to analyze the steady-state response over a range of frequencies, emphasizing the visualization of poles and zeros affecting the frequency response. Examples are provided to illustrate the design and simulation of bandpass filters, along with the analysis of series RLC bandpass circuits and pole loci.
