Hi, My teacher gave me the following information and asked me to prove that 1 minute of music requires 10 MB of storage space in a CD. Sampling Rate: 44.1 kHz Bit Depth: 16 bits No. Channels: 2 I am a bit confused. If the bit depth is 16, that means I have 4 bits. But I only get the correct answer when I use 16 bits. Should instead of Bit depth it say number of bits? Thanks, Peter G.
