  Converts a direct form filter into a series connection of
  second-order filters.

DPZPLOT.M Exercises 10.1
  Plots the poles and zeros of a discrete-time linear system.

DTFTSINC.M Exercise 5.1
  Calculates samples of the discrete-time sinc function.

EYEDIAGRAM.M Exercise 8.4
  Plots the eye diagram for a pulse-amplitude-modulated (PAM) system.

PZPLOT.M Exercises 9.1

  ORIG.MAT, as well as the coefficients of three lowpass filters used
  to process this noisy signal.

PLUS.MAT Exercise 6.2
  A 32-by-32 element gray-scale image of the "plus" sign.

PROTOH.MAT Exercise 6.3
  The impulse response of an approximation to an ideal lowpass filter
