Show transcribed image textRose samples some voltage data. Her input voltage signal is fsignal = 80 Hz with amplitude = 2.00 V. Some noise is also present in the input voltage: fnoise = 3600 Hz with amplitude = 0.150 V. She uses an A/D that is 14-bit. with a range of -5 V to +5 V. She uses a Butterworth low-pass filter to remove the noise. If the filter cutoff frequency is set at 100 Hz. calculate the minimum order of the filter such that the noise is completely gone (attenuated so much that the A/D converter can no longer recognize it). Give your answer to 3 significant digits, but recognize that filters typically have filter orders n = 1, 2, 4, 6,... What is the minimum order of a real filter that Rose can actually use that will eliminate the noise?
