(a) Skętch a diagram of the 8-pin operational amplifier and indicate the function of [6 marks] each pin. State four (4) application areas.of an operational amplifier. (b) Sketch the circuit diagram of the differentiator circuit and derive an expression for the output of the circuit at time t 0. Assume the input voltage to the circuit is [7 marks] Vin = 2cos3000nt, R = 100k2, and C 0.02pF. (c) A triangular input voltage v (t) with the following characteristics is applied to the differentiator circuit in 4 (b) above: v (1) = 0 at r = 0V, v (t) = 4V at t = 2ms, v %3D %3D %3D (r) = 0V at i = 4ms, v (1) = -4V at t = 6ms, and v (1) =0V at / = 8ms. Sketch the %3D input voltage and derive an expression for the input voltage signal. Find the output [7 marks] signal voltage signal from the differentiator and sketch the signal.
