Unformatted text preview: out /V in for the filter below. What type of filter is this? Sketch the v out (t) when v in (t) is a unit step function and v out (0) = 0 (you do not need to perform detailed calculations; you can base your answer on your knowledge of the type of filter and what v out is at t = ∞ ). Question 4 (1+1+2+1 points): (a) For the circuit shown here, assume the OPAMP is ideal (infinite gain, infinite input resistance, zero output resistance, etc.). What is the value of current I 1 ? (b) Find the voltage V 1 . (c) Find the output voltage V out . (d) A real OPAMP is not a 3-terminal device. What terminals have not been drawn below? V in V out 1 k Ω 1 k Ω 1 pF 1 nH V 1 +-I 1 V in V out R 1 R 2 R 3 V in V out C R R t 1 v in (t)...
