Document Summary
Sysc 4405: midterm exam (#:3) october 24, 2008. Background: you are working for a recording company that wants to make its music sound like it was recorded in a concert hall, rather than in a small recording studio. You are given the job of creating a dsp model of a concert hall, which can be applied to music during digital mastering. To do this, you rent a conference hall, and conduct the following test. A musician plays her instrument on the centre of the stage, which is recorded at a microphone (as x(t)). In the centre of the audience, a technician records the sound at another microphone (y(t)). You determine that the recorded sound is the sum of weighted contributions from four paths, each with a different delay. Thus y(t) = x (amplitudei)x(t delayi) i paths. 0. 05: (1 point) your exam is exam number 3.
