1. This is poorly represented by traditional methods, which motivates time frequency analysis . 2. This approach is particularly studied in signal processing, under time frequency analysis . 3. These signal properties can be extracted from neural recordings using time-frequency analysis . 4. The most common technique for detecting faults is the time-frequency analysis technique. 5. Frequency analysis is also impossible because the same letter is always enciphered differently.6. Frequency analysis relies on a cipher failing to hide these statistics.7. Frequency analysis is the basic tool for breaking most classical ciphers.8. Frequency analysis indicated approximately 2 % of the Chinese population carry the allele.9. The frequency analysis of bigrams is possible, but considerably more difficult. 10. So a frequency analysis shows an approximately ( pseudo ) random number generator.
