11–89 OP AMP Modules and Loading Figure P11–89 shows an interconnection of three basic OP AMP modules.

(a) Does this interconnection involve loading?

(b) Find the overall transfer function of the interconnection and locate its poles and zeros.

(c) Find the steady-state output v2ðtÞ when the input is v1ðtÞ = cos 500t V. Repeat for v1ðtÞ = cos 10 kt V and again for v1ðtÞ = cos 200 kt V.

(d) Can you think of a use for this circuit?
