Extracted text: (a) Explain how a 2nd order Low Pass Filter differs from 1st order High Pass Filter in operation, pole and slope. (b) Design a 1* order Band Pass Filter using op-amp with fHC = 18KHZ, fic = 3KHZ and pass band gain, Av of +10. Let +Vcc = 15V, –Vee = -15V, RF = R1 = R3= 240KN and C = 47NF. Draw the circuit using standard resistance values.
