An engineer builds a light detection system. To avoid problems with sunlight (DC light) and lights from the building (60 Hz), the engineer pulses the transmitter at 600 Hz. Design an amplifier for the receiver that filters out light below 6 Hz, notches out signals at 60 Hz, amplifies signals at 600 Hz and filters (2ndorder) signals above 6 kHz. For practical purposes use z
