What is the purpose of a CODEC?

🔍 Key Concepts

• CODEC stands for "coder-decoder" or "compressor-decompressor" • How analog voice is changed so it can travel over digital systems (like DSC, VoIP, or digital radios) • Difference between data communications in general and the specific role of a CODEC

💭 Think About

• Which option describes a function that must happen any time you send normal spoken voice over a digital radio or digital network? • Does a CODEC mainly create the communication (like distress or data), or does it prepare/transform the signal so it can be carried by those systems? • Look for the choice that focuses on changing the form of the signal rather than the purpose of the communication.

✅ Before You Answer

• Identify which answer talks about changing analog voice into digital form (and back again). • Separate functions like distress enabling or noise canceling from the basic signal conversion process. • Ask: could the same device be used for many types of communication (voice, distress, routine) as long as it converts analog ↔ digital?
