3. What is sample rate?
- Bit depth and sample rate will affect loss of information.
- Bit depth and sample rate will affect loss of connections.
- The number of samples taken per second (frequency).
- The amount of information in the sample and its affects the value that can be given to the amplitude per sample and so will affect the accuracy of the sample.
