A proximity (displacement) sensor on your car is represented by a voltage signal vin(t). 1V corresponds to a displacement of 1 mm from the reference position of the sensor target. The car is moving directly towards the sensor target. Provide an op-amp circuit that produces a voltage V1(t) that is proportional to the:
velocity with which the car is moving relative to the sensor target. Design it such that 1 V output represents a velocity of 1 mm/s
