File size (bits) = sample rate x resolution x time
How do you find the resolution? Do they give it you in the exam?
Calculate the file size in bits for a two minute sound recording that has used a sample rate of 1000 Hertz and a sample resolution of 5 bit
One way of representing sound digitally is to take samples of the original sound. Define sampling rate
Define sampling resolution
To calculate the storage requirements that will be needed to store sound samples you need to know both the sampling rate that will be used and the sampling resolution that will be used. Explain how to calculate the storage requirements for the sampled sound data.
Hope this helps
