Q1. (a) Show an opamp circuit that can perform 1st order derivative of a time function, f(t). df (t) dt Specify the resistor and capacitor values so that the coefficient of the 1st order derivative is 1. (Note: Polarity of the implemented function is not important) f' = (b) The temperature at a place can be described by the following time function, f(t): f(t) = a3t³ + a₂t² + a₁ +ao, which exhibits the following characteristic as shown in Fig. Q1: Temperature (°C) T₁ T₂ Time (hour) Fig. Q1 (i) Determine the 1st order derivative of f(t), and estimate T and T₂ in terms of a3, a2, ai, ao. (ii) An engine will be turned on between the interval of T, and T₂. Devise a circuit that will generate an EN signal that will be high during the interval between T₁ and T₂.
