Ok here's this question that I can't do :
**broken link removed**
I'm only not sure about part d , if the music signal is bandlimited to 15kHz , then the sampling frequency of the music signal should be 30kHz right? But the answer stated that the sampling frequency was supposed to be 32kHz. I don't understand why it is like that , is there something they I'm supposed to know about music signals? If that is the case , then what other kinds of signals have their sampling frequency derived in the same way? I'm really confused.
Thanks for the help!
