assignment project 4 voicing measures answer sheet

you are setting up a pair of pa speakers on a field in preparation for an outdoor event. each speaker is 0.65 m wide, and the speakers are separated by 8.2m. to test the speakers, your coworker plays a single tone through the speakers whose frequency is 440Hz. you are standing 52m directly in front of the speakers and facing them. roughly how far would you have to walk to your left or right to hear the sound amplitude drop to zero? how much farther would you have to go to hear the amplitude go back to its original strength ?

You are sampling a signal, with a sampling frequency of fs = 2000Hz. There are three frequency components of the signal, f₁ = 400Hz, f2 = 1200Hz, and f3 = 2100Hz. What are the frequencies that you will see? f1a f2a f3a Question 14 Question 15 Question 16 Hz Hz Hz If each of the original frequencies has an amplitude of 1.0 V, and you pass the signal through a passive low-pass filter with a cutoff frequency of 1200 Hz, what are the measured amplitudes of the signals. As a reminder, the Magnitude ratio of a low-pass filter is M(f) = √√₁+(+)² Ala Question 17 V A2a Question 18 V A3a Question 19 V

I need help answering these questions please

Can you please provide the MATLAB code needed to answer a, b and c? I am new to MATLAB and don't know where to start. Thank you!

sorry and why did you double the frequency again form 100 to 200  do you mind explaining why please thank you .

Given R1=1k and R2=10k, what is C so that [Vout/Vin|=0.1 when the frequency of Vin is 3322 Hz? C R2 Vin R. Vout

Draw the waveforms of Q0, Q1, Q2 (all initialized to zero) What is the countering sequence of the following circuit? Is it an asynchronous counter or a synchronous counter? Why?

Kindly solve it with complete solution so that I can understand. Thanks
