KEY DIFFERENCES BETWEEN ANALOG AND DIGITAL SIGNALS

  • An analog signal is a continuous signal whereas Digital signals are time separated signals.
  • Analog signal is denoted by sine waves while It is denoted by square waves
  • Analog signal uses a continuous range of values that help you to represent information on the other hand digital signal uses discrete 0 and 1 to represent information.
  • The analog signal bandwidth is low while the bandwidth of the digital signal is high.
  • Analog instruments give considerable observational errors whereas Digital instruments never cause any kind of observational errors.
  • Analog hardware never offers flexible implementation, but Digital hardware offers flexibility in implementation.
  • Analog signals are suited for audio and video transmission while Digital signals are suited for Computing and digital electronics.
