Digital Transmission Technologies Quiz

Digital Signal Transmission Methods

• Pulse Amplitude Modulation (PAM) is the most commonly used method.

Digital Transmission System Components

• Modulator: Conerts digital signals to analog signals
• Demodulator: Conerts analog signals to digital signals
• Line Coding: Transforms digital data into a signal suitable for the transmission medium
• Regenerators: Amplifies and reshapes digital signals to combat degradation
• Multiplexers: Combine multiple data streams into a single transmission channel
• Demultiplexers: Separate multiple data streams from a single channel

Digital Transmission System Purpose

• To transmit digital data efficiently and reliably over different media
• To ensure that data arrives at the receiver without errors

Synchronous Digital Hierarchy (SDH)

• SONET (Synchronous Optical Network) is the standard protocol associated with SDH for optical fiber networks.

Multiplexing in Digital Signal Transmission

• Multiplexing combines multiple data streams into a single transmission channel, allowing for more efficient use of bandwidth.

This quiz covers PCM, PDH, and SDH technologies in digital transmission, focusing on practical operational aspects. Topics include wireless and wired transmission technologies, as well as major communication protocols. Ideal for students seeking a practical understanding of digital transmission technologies.
