Chapter 5 Solution To Problems
Answer: The overall C/N for the T1 carrier is the same as for the TV carriers, 26.0 dB. The T1 carrier gets less power, but also is received against a lower noise background because of its narrower bandwidth. The effects are in proportion, so the C/N value is the same for both the carrier and the T1 signal. 5. ... Doc Viewer
