JY OF ENGINEERING QUESTION No 1: DEPARTMENT OF TCE (10 POINTS) Generating the Bell Envelopes Now we take the general FM synthesis formula (l) end specialize for the case of a bell sound. The amplitude envelope Alt) and the modulation index envelope (for the bell are hoth decaying exponentials Thar is, they both have the following form where is parameter that controls the decay rate of the exponential Notice that you and yt) Lle. so is the time it takes a final of the form (3) to decay to de- 16.8% of initial vahie Fortes Tohon the parameter is called the time constant ( Usesc previous cstion to write a MATI.Atact that will remote a decals sprema be used later in synthesis a bellund. The file biter booklet function yy-bellen xtau, due fimpl. BELLEN produces en function to be belona, dr, amp * 36 which is consi dur-duration of the evelope %6 pling frequency Ted yy saying exponential cnvelope 96 note: produces exponential decay for positivo (b) Use your face to produced following Sampling Frequery Tool - durat5 38 ThinkPad
