Crest Factor of Band Limited Pseudorandom Noise.

摘要

This memorandum describes briefly laboratory tests that were conducted to determine sonar source level limitations due to amplitude modulation when using pseudorandom noise transmissions. These tests did demonstrate the degree of loss that might be expected when this type of signal is utilized in a peak power limited system. The numerical results obtained from these tests appear sufficient to answer some of the initial questions which have been raised concerning this degradation in power.
