Question

1----You are working for a company that has developed a new speaker that is supposed to reproduce any and all signals in the frequency range of 20 Hz to 20 kHz with a flat frequency response. You have been selected to test the speaker in order to verify the operation. You are supplied with a microphone that has a flat response, a perfect power amplifier, a white noise generator, and an anechoic chamber. How do you utilize Fourier transforms to test the speaker?

2----What is the relationship between the Laplace transform and the Fourier transform? Provide numerical examples to illustrate your points.

3---Now that you are performing the final assembly of your system, what would you add if you had more time?

4---What are some possible uses of your project? Include possible spinoffs.

Ans. 1 
 The task is to test the speaker with the help of Fourier series. The given equipments 
are microphone, flat response, perfect power amplifier, a white noise generator and 
an echoic chamber.  
 The given frequency range is 20 hz to20 khz , which is the human audible 
frequency range. The use of microphone is for speaking purpose in the microphone 
and the flat response is for the wave output measurement and the noise generator is 
for producing the noise waves.  
 
 The strategies to adopt for the testing of the sound waves are: 
 LMS ( Gated tonebust ) 
 TEF (Swept Sinewave )  
 MLS (Maximum length sequence) 
The output form will be as:
