Tasneem was designing a pulse rate measuring circuit for his Junior Design Project. After implementing the circuit with a pulse rate sensor, he noticed that there were both low and high frequency unwanted noises in the recorded pulse signal. Since human pulse rate ranges between 60 to 180 bpm, he decided to use an analog filter that eliminates the signal components below 0.5 Hz and the ones above 5 Hz. He used two op-amps, two resistors, and two capacitors in the filter circuitry. Additionally, he provided an overall gain of +100% (a) Fill in the blanks: Active/Passive RC/RL/RLC 1st/2nd/3rd/4th order LPF/HPF/BPF/BRF What kind of filter is he using? What is/are his target cut-off frequency(or frequencies)? [20] Write the equation(s) of the cut-off frequency (or frequencies) for this filter (b) Draw the complete circuit diagram of his design. Show the assumed and calculated values of all passive circuit components used in the filter circuitry. [20] Tasneem was designing a pulse rate measuring circuit for his Junior Design Project.
