2. Signal Space Concepts

  title={2. Signal Space Concepts},
  author={Robert G. Gallager},
Most of the waveforms that we deal with will be real, and pictures are certainly easier to draw for the real case. However, most of the results are the same for the real and complex case, so long as complex conjugates are included; since the complex conjugate of a real number is just the number itself, the complex conjugates simply provide a minor irritant for real functions. The Fouier transform and Fourier series for a waveform is usually complex, whether the waveform is real or complex, and…
