1. In radio applications, intermodulation may be measured as adjacent channel power ratio . 2. In the uplink LTE uses both peak-to-average power ratio ( PAPR ). 3. Although smaller, it had a superior weight to power ratio . 4. Today's guns show a size / power ratio undreamed of 25 years ago ." 5. As it is a power ratio , it is normally expressed in decibels ( dB ). 6. At . gross weight the aircraft had a weight to power ratio of . per horsepower. 7. A change in power ratio by a factor of 10 corresponds to a change in level of. 8. Therefore, engineers tried to minimise the weight-to-power ratio , and short-distance connections between planes and the ground became possible. 9. In exact terms the power ratio is 10, or about 3.9811, a relative error of about 0.5 %. 10. For other waveforms, the relationship between peak power and average power is the peak-to-average power ratio ( PAPR ).
