Question

Hello :).
Continuing with my learning process I have decided to try another exercise, you could show me how to do it correctly to compare with what I have done in the notebook. Thank you ^_^

First exercise:
Where x(t) = Asen(2*Phi*Fo*t) where the frequency Fo = 2000 Hz resolves:
* Aliasing phenomenon occurs if x(t) is sampled at S = 4500 Hz? Explain step by step if alias is found, find frequency Fa.
* Aliasing phenomenon occurs if x(t) is sampled at S = 3500 Hz? Explain step by step and if it presents alias, find the frequency Fa.
Second Exercise:
A sine wave with amplitude levels of -2V and 2V will be sampled and quantized by rounding with an error rms = 10 mV.
How many B-bits are required?
Third exercise:
Search the algorithm for the Transformed Fourier's discreet, in which the summation must be raised
of transformed. the signal is : x[n] = [8 8 2]

Answer 1

Hello,
          Please find the answer attached as under. Please give a thumbs up rating if you find the answer useful! Have a rocking day ahead!

For Q3, I didn't quite understand the question. What do you mean by " in which the summation must be raised of transformed." ?
