Problem
1. Show that frequency shifting and phase rotation do not affect the statistical properties of zero-mean white Gaussian noise.
2. What is the round-trip path delay for a 60-rn path with CT-2? Does this amount of delay explain the allocated guard intervals?
3. The maximum frequency error allowed in the CT-2 standard is 10 kHz or less. What is the relative frequency error, expressed in parts per million (ppm)?
