Cascaded Op Amp System Assume ideal operational amplifiers therefore you can use summing point constraints. Write time-domain equations for v3(t), v4(t), and v5(t) in terms of the circuit elements. Observe, no calculations are required. v1(t) = R3 C1 v3(t) v1(t) v2(t) = R1 R4 v4(t) v2(t) v3(t) = R2 v4(t) v5(t) v5(t) =
