(a) A signal transmission line will be used to carry measurement data as a frequency modulated signal from 8 kHz to 10 kHz. The line is shared with voice data below 600 Hz, and switching noise occurs above 150 kHz. A band-pass RC filter is used to reduce the voice by 80 % and the switching noise by 90 %. Use resistance ratio of r =0.01. (1) Design a band pass RC filter by using the available electronic components which are two capacitors (4.7 pF and 2.46 nF) and two resistors (2.2 M1 and 22 k 2). With the filter design, determine the low band frequency (fi) and the high band frequency (f). Draw the band pass RC filter with proper labeling. (ü) Based on the band pass RC filter design in Q4 (a)(i), evaluate the attenuation of the measurement data if the frequency modulated signal is operated at 9 kHz.
