v, - ""J ._-____. Questions 1012 refer to Figure 8-17, which shows the glottal wave of a person as a function of position at time t ' 0 5. Assume that this wave can be constructed by Fourier's theorem using a harmonic series with all modes present. Assume that the speed of sound in air is 335m/s. IO.
