註釋
Methods to determine time or frequency by reception of NBS high frequency radio broadcasts are discussed. Results are shown for calibration of time signals to within +/- 100 microseconds and calibration of frequency offset with a resolution of better than 1 part in 109. These results are achieved by using a systematic approach and refined measurement technique.
