What questions need to be answered?

• How Fat and Protein are related to the step response at certain Frequencies.
• Find the range of frequencies for fat and protein in fresh Milk.
• Find the step response of

How will it be evaluated?

Finding a correlation between Step response and Fat Protein that could be measure with the DAC and DCA modules. - By being used in an actual farm.

Note: As week22 I’ve decided to change this to the next testing plan also written in week19 documentation

For the testing I’ve changed my idea since the time available is less for me. My testing will be to measure different samples:

• 100ml From a bottle milk
• 100ml of creme.
• 100ml of coca-cola
• 100ml of tap water.

I’ll take note of the values of the samples and compare the results in a table like this:

Substance	Samples per second	Min	Max	Average
