Questions and Answers

What is the difference between continuous time and discrete time signals?

  • Continuous time signals are specified at discrete points of t = nT
  • Discrete time signals are specified for every t
  • Discrete time signals only take finite number of values (amplitudes)
  • Continuous time signals take an infinite number of values (amplitudes) (correct)
