Flashcards
0/10
Hardware Complexity
Advantages: Digital systems often require less complex hardware. Disadvantages: Analog systems may require specialized equipment which can be expensive.
Latency
Advantages: Analog signals do not have encoding or decoding delays. Disadvantages: Digital systems experience latency due to signal processing and buffering.
Continuous Variation
Advantages: Analog signals match the natural continuity of sound waves. Disadvantages: More susceptible to noise and degradation over distance.
Storage and Replication
Advantages: Digital signals are easy to store and replicate without loss of quality. Disadvantages: Digital storage requires encoding and can be limited by data format compatibility.
Connection and Compatibility
Advantages: Digital devices can easily interface with computers and networks. Disadvantages: Analog signals often require specific connectors and are not universally compatible.
Signal Processing
Advantages: Digital signals are easier to process with computers. Disadvantages: Requires analog-to-digital conversion which may introduce quantization errors.
Resolution and Fidelity
Advantages: Analog signals can theoretically provide infinite resolution. Disadvantages: Digital signals are limited by bit depth and sample rate.
Signal Bandwidth
Advantages: Digital signals can include more information within the same bandwidth. Disadvantages: Analog signals may experience bandwidth limitations.
Robustness to Noise
Advantages: Digital signals are less affected by noise due to discrete values. Disadvantages: Analog signals can degrade due to noise throughout the signal path.
Durability and Longevity
Advantages: Digital formats are more durable over time. Disadvantages: Analog media can degrade with each playback and over time.
