1. No such inverse procedure is known for the periodogram method. 2. A common non-parametric technique is the periodogram . 3. Periodogram -based techniques introduce small biases that are unacceptable in some applications.4. KZ filter can be used to smooth the periodogram . 5. This computed PSD is sometimes called a periodogram . 6. Determinations of sharp frequency lines in the spectra can be determine by adaptively smoothed periodogram . 7. The central idea of the algorithm is adaptively smoothing the logarithm of a KZ periodogram . 8. 4 . The periodogram under consideration can be modified by multiplying it with a window function. 9. The starting value for the frequency can be obtained from the dominant frequency in a periodogram . 10. Many other techniques for spectral estimation have been developed to mitigate the disadvantages of the basic periodogram .
