EECS 314 Winter 2009 Homework set 9 Student’s name ___________________________ Discussion section # _______ (Last, First, write legibly, use ink) (use ink) Instructor is not responsible for grading and entering scores for HW papers lacking clear information in the required fields above © 2009 Alexander Ganago Page 1 of 1 Problem 2 Memory required for data storage (40 points) The Big Picture As you know from lecture notes, music on CD is recorded with 16‐ or 20‐bit resolution, at the sampling rate of ~ 44 kHz. As you know from reading the labels, a blank CD has the capacity of 700 MB (megabytes; 1 Byte = 8 bits; 1 MB ~ 10 6 Bytes) and is rated for 80 minutes of music recording. In this Problem, you will “put 2 and 2 together” in order to see whether all of the above numbers make sense. The Assignment Assume that the music is recorded in two channels (stereo = left and right) that have the same resolution of 16 bits and the same sampling rate of 44 kHz. Calculate the amount of memory in MB required to record a song that lasts 2 minutes and 48 seconds. Your answer: _____________________ MB Repeat for 20‐ bit recording: Your answer: _____________________ MB Assume that a blank CD has the capacity of 700 MB. Calculate how many minutes of music can be stored on the CD.
