Digital Transmission: Advantages

• Produces fewer errors

  • Easier to detect and correct errors, since transmitted data is binary (1s and 0s, only two distinct values))

• Permits higher maximum transmission rates

  • e.g., Optical fiber designed for digital transmission

• More efficient

  • Possible to send more digital data through a given circuit

• More secure

  • Easier to encrypt

• Simpler to integrate voice, video and data

  • Easier to combine them on the same circuit, since signals made up of digital data
