3. A Leslie speaker was a type of speaker available for Hammond Organs. Please research how a Leslie speaker works and write a description of how you would simulate it in software. Be sure your simulation takes into account both the doppler effect and the tremelo .

Explanation:

1.A filter that would eliminate 294 will have to be 294/44100 * 360 degrees.

The coordinates on the unit circle will be-> cos(2.4 deg), sin(2.4 deg).

So now, The zeros will be (cos(2.4) +-sin(2.4)j).

Transfer function z+= (cos(2.4) +-sin(2.4)j)/ z.

2. yt=xt + .05yt-35280

3.The Leslie speaker has an amplifier, and a pedal drive slow and fast speed setting- Chorale and Tremelo. So as sound rotates around specific pivot point, it produces the modulation of amplitude, or Tremelo.

The below equation would be used to demonstrate the doppler effect, where c is the velocity of waves. Vr will be the receiver velocity relative to medium. And Vs is the velocity relative to the source.

             f =[ c + vr}  f⁰

                 [ c +vs]

For tremolo we can have sin(x)*original signal’s amplitude to get some amplitude variance
