A mixer circuit using an ideal operational amplifier (op-amp), A is shown in the Figure 1 below. Signal y(t) represents the output signal whilst signals x1(t) andx2(t) represent the input signals. All the resistors are ideal with same resistance, which is 10KQ. y(t) A x:(1) RI R3 x:(t) R2 Figure 1 (a) Determine the expression of the output signal, y(t) in terms of the input signals x,(t) and x2(t). (b) Determine whether the output signal, y(t) belongs to the system classifications below against the input signals x,(t) andx2(t): i. Time-varying or Time-invariant ii. Linear or Nonlinear ii. Instantaneous or Dynamic iv. Causal or Non-causal V. Open loop of Closed loop Provide the necessary mathematical calculations or statements to support your arguments.
