Question: What is the minimum number of speech samples required for processing by both the AMR encoder and decoder, as per the Adaptive Multi-Rate (AMR) speech codec specifications?
Option 1: 80 samples
Option 2: 160 samples
Option 3: 240 samples
Option 4: 320 samples
Explanation: According to the AMR speech codec's processing rules, both the encoder and decoder process complete frames only. Each frame is composed of a fixed number of speech samples. The correct minimum number of samples per frame for processing is 160, as this aligns with the specified frame size that allows for efficient encoding and decoding without partial frame processing.
