RI M V +1 (+) n R3 • R₂ 1 R3 1. In the circuit shown above, Vj = 9V, V2 = 12V, R = R2 = R3 = 1 kN. Analyze this circuit using the superposition method: = (a) Draw the circuit with Vi alone, then hand calculate the contribution of V; to the current through R3. (b) Draw the circuit with V2 alone, then hand calculate the contribution of V, to the current through R3. (c) Calculate the current through R3 in the original circuit when both sources are active.
2. Build the circuit shown in Figure 1 in LTspice (when both sources are active). Determine the current through R3. Vin Vout (L. 3. In the above circuit, Vi is a square wave with V = 1V, = 1 kHz, and the duty cycle is 50%. R = 1 ks and C = 1JF. • Build the circuit in LTspice and do a transient analysis for four cycles. . Plot Vin and Vout
