      2      Frequency Domain Analysis:  Bode magnitude and phase
             response of lowpass, highpass, bandpass, bandstop, and
             allpass filters.  Delay analysis.  Dominant pole-zero analysis. 

      3      Time Domain Analysis:  Impulse and step response of lowpass,
             highpass, bandpass, bandstop, and allpass filters.  Time
             domain approximations using Elmore's results, dominant
             pole-zeros, and Valley and Wallman results.

      4      Classical Filter Responses:  MFM, Butterworth, Chebyshev,
             ultraspherical and Legendre, Papoulis, inverse Chebyshev,
             elliptic, MFD, Bessel, equiripple delay, Gaussian,
             synchrously-tuned, parabolic, catenary, elliptic contour,
             and transitional filters.  Noise response of filters.

      7      Active Filter Classification: Signal flow graphs, 2nd order
             RC active filters, first and second-order decompositions,
             Class A, A_, B, C, C_, D, and E filters.

      8      Lowpass Filters:  Lowpass filter classes, filter design
             sheets, lowpass filter  compilations, component selection,
             lowpass filter design examples, gain-tuned lowpass filters,
             passive-tuned lowpass filters, immittance calculations, high-
             frequency filters, alternatives to cascade design.

	software), build, and test a 4th order lowpass filter.
