b. Choose suitable values for capacitors and resistors to get a critical frequency of (a+B+200) kHz for the filter in Figure-5. (Assume Ra-Ra+1, Ca=Ca+1). c. A filter circuit diagram is given below in Figure-5. Copy the diagram and mark the possible outputs you can get from the circuit clearly on the diagram. EX: High pass, Low pass, Band pass, Band stop...etc. Please note that you could get negative marks for any wrong answers in this section. = B (Replace a and B according to the given instructions at the top of the paper. If a = replace ß with B+1) св Ra www Ca Ra ww RB www Vin Ca CBξRB Rb Rd Figure-5 d. Modify the circuit given in Figure-5 to get only one active low pass output and one active high pass output (The circuit should give only two outputs). You cannot add any extra op- amps or other circuit components except wires. Draw the circuit diagram. (Replace a and B according to the given instructions at the top of the paper. If a = = B replace B with B+1). 4 (20 marks) e. Write equations for the cut off frequencies of the high pass filter (fc1) and low pass filter (fc2) of the modified circuit you made in part (d) and calculate for the given values below.
