Fundamental frequency and period detector processes and systems which determine the end of a cycle of an ac waveform by using the characteristic of the integral of a single cycle of an ac waveform that the value of the integral at the end of the cycle is the same as at the cycle start ...
How to find even and odd parts in frequency domain? Why are Fourier transforms complex? What is the fundamental period of a function that is the sum of two-period functions? Why are two variables independent if their relative frequency values are equal or very close to equal?
The fundamental frequency (f phi) of the first five periods in the acoustic wave form of vowels following stop consonant productions and the f phi of a period approximately 100 ms into the vowel were analyzed in the repeated fluent utterances of 10 nonstutterers and 10 stutterers both pre- an...
This paper investigates this phenomenon in an effort to explore the discriminating ability of jitter (period-to-period fluctuations in fundamental frequency) among suicidal and nonsuicidal patients. First, a wavelet transform based glottal cycle duration estimation technique is employed for the voiced/...
A period fitting method, which is a variant of the classical least-square fitting method, is proposed to determine the fundamental frequency of a physical oscillator. The root mean square deviation used as the criterion in this method is a single-parameter function of the fundamental frequency of...

site fundamental period; frequency; ground motion amplification; resonance1. Introduction It is now widely recognized that soil characteristics, particularly those of near-surface soil deposits, have a substantial effect on structural performance during intense strong ground motion [1]. Shallow soil ...
