Filter noise by using average method

[MyHuong]

Lease help me, I have an assignment that ask me Filter the nois of this function
f(x)=cos(0.1t) + noise
the noise is random number between -0.5< n < 0.5
Filter the noise out using the average noise method? ( in excel )
Thanks

We do not do your homework for you. What can you tell us about how to use DSP to perform this filtering? What kind of filter (LPF, BPF, HPF) do you think you need to set up?

I would recommend using the average noise method to filter out the noise from the given function. This method involves taking multiple measurements of the function and then calculating the average value, which will help to reduce the impact of the random noise.

In order to implement this method in excel, you can follow these steps:

1. First, create a column for the function values and a separate column for the random noise values.
2. Then, add a third column where you will calculate the average value by taking the sum of the function values and the noise values and dividing it by the total number of measurements.
3. Next, subtract the average value from the function values to get the filtered values.
4. Finally, you can plot the filtered values to see the impact of the average noise method on the original function.

Using this method, you should be able to effectively filter out the random noise and get a clearer representation of the original function. I hope this helps with your assignment. Good luck!
