51. The vocal tract configuration for fricatives influences the filtering of the sound source by causing anti -resonance .
Anti resonance it is the filtering effect of the vocal tract characterized by loss of acoustic energy in a particular frequency region.
50.Draw a stylized vocal tract configuration for a typical fricative. 51.Describe how the vocal tract configuration...
B. a) Draw a half adder using only NAND gates. b) Describe how 3 to 8 line Decoder circuits works and indicate typical inputs and outputs. Also provide a carefully labeled "black box" diagram. ANS:
12. For surface plasmon resonance (SPR), answer the following questions: a) Describe the experimental set-up of the Kretschmann configuration to excite a surface plasmon in a metal thin film? b) Draw the experimental set-up, how does the laser beam interact with the metal thin film, what is its polarization etc. label everything clearly c) For the case of Gold thin film with ε--10 with air as the dielectric medium ε-1, if the prism has an index of refraction n-1.6 at...
