You would like to make high resolution recordings on your computer of some of your record collection. You wish to use a sampling rate of 96 kHz with each sample 4 bytes.

For full marks, you must show all your working.

• i.How many bits are there in each sample?
• ii.How many bits per second are processed while the music is being recorded? Express your answer in scientific notation to 3 significant figures.
• iii.The piece of music is 4 minutes 30 seconds long, how many bits are processed in total? Express your answer in scientific notation.
• iv.If the sampling rate is reduced to 46 kHz how many bits will be processed using the same piece of music? Express your answer in scientific notation to 3 significant figures.
• v.What is the percentage decrease in the number of bits processed as a result of reducing the sampling rate from 96 kHz to 46 kHz. Express your answer to 2 decimal places.
