R1 and r2 values should be the same and c1 and c2

R1 and R2 values should be the same, and C1 and C2 values
should be the same. Please note that there are numerous
combinations of resistor and capacitor values that could
provide the same cutoff frequency calculations, but try to
keep the resistor values between 1.0k Ohms and 10.0k Ohms.
Calculate the design values of the resistors and capacitors
and record all values in Table 1 in the Week 3 iLab cover
report.
Because it is highly likely that you will not be able to find
actual resistor and capacitor components that match your
calculated values, try to find values as close as possible to
the calculated values for use in your circuit construction, and
record them in Table 1 in the iLab cover report. If you cannot
find close enough values, you will need to redo the design
calculations.
Calculate the -3dB frequency from the actual component
values used for the circuit. Please keep in mind that all
components have a tolerance factor and that your test
measurements will reflect this.

the information into the Week 3 iLab cover report.

In Excel and using the measured filter response recorded
data, create a graph showing all of the information similar to
what is shown in Figure 3 below. Copy and paste your graph
into the Week 3 iLab cover report. Please remember that
graph, axes, and titles are part of the documentation and are
part of the requirements to be met for grading.

In this portion of the lab, you will use the MA FIR
CodeWarrior project for the Tower board and ADC and DAC
board in order to implement and test a moving average filter
of length 9.
