Sampling

---

1. I have a track of audio with a maximum frequency of 3 kHz. What should be my sampling frequency if I want to digitize it?

[2]

3 kHz * 2 = 6 khz

2. At a concert, Coldplay's sound-system has a base frequency of 15 Hz to 15 kHz. At what rate might their record company like to sample their 'music' to make a nice, high quality CD of it later?

[2]

15 kHz * 2 = 30 kHz
