The matlab code below creates a sinusoid and plays it as a single tone: tt e: (1/4000) : 9; xx cos (2*pi*13000*tt soundsc(xx, fsamp) + 0.7*pi); although the sinusoid was not written have a frequency of 5700 hz, it is possible to play out the vector xx so that it sounds like a 5700 hz tone. determine the value of fsamp that should be used in the soundsc) command to have the sound be a 5700 hz tone. hint: analyze the code. don't run it.
