Note that the reflection coefficients for the junction of two lossless acoustic tubes of areas Ak and Ak+1can be written as either(a) Show that since both Akand Ak+1are positive, −1 ≤ rk ≤ 1. (b) Show that if 0k<>k+1<>k
By substituting the appropriate matrices Qˆ1and Qˆ2into Eq. (5.80), show that the transfer function of a two-tube discrete-time vocal tract model is given by Eq. (5.82).
