C. Design of an RC filter: Assume that you now have a desired signal of 1cos(27100t) and some unknown high frequency noise. Select a cutoff frequency for a LPF in which the 100Hz signal is NOT attenuated. Desired f Using the components in your lab kit, select an appropriate R and C to produce a cutoff frequency close to your desired fe Build this circuit using the values you chose. Let vin be the Function Generator (notice we are removing the DC power supply completely for this step). Set the function generator's output to be: 1cos(2pi F). Modify F and fill out the following table. INPUT Magnitude (in Volts) 1 1 1 1 1 1 1 INPUT Frequency (in Hz) 1 10 100 1k 10k 100k 1M Vin R OUTPUT Magnitude (in Volts) с At what frequency would you consider the noise "attenuated"? Explain your answer. ANSWER: Vo
