Frequency Response of LTI Systems — Filters Revisited from the Signals Side

Inside this lesson
  • Define H(jω) as the Fourier transform of the impulse response h(t) and relate it to the general transfer function H(s) at s = jω
  • Derive the frequency response of a first-order RC low-pass filter from the impulse-response viewpoint
  • Compute the magnitude |H(jω)| at arbitrary frequencies using the RC low-pass formula
  • Connect the impulse-response derivation to the Bode-plot results from the Circuits course
