Response to the following problem:
1. Write a program for the detection of voiced and unvoiced segments using the AMDF function. Test your algorithm on the test . snd sound file.
2. Select a voiced segment from the test . raw file. Find the fourth-, sixth-, and tenthorder LPC filters for this segment using the Levinson-Durbin algorithm. For each of the filters, find the multipulse sequence that results in the closest approximation to the voiced signal.
Make sure you use enough details to support your answer.
