Draw a transfer characteristic relating v_o to v_i for the positive clipping network of Problem 2.17. Also, sketch one cycle of the output waveform if v_i = 10 \sin ωt \text{V}.
The diode blocks for v_i < 6 \text{V} and conducts for v_i ≥ 6 \text{V}. Thus, v_o = v_i for v_i < 6 \text{V}, and v_o = 6 \text{V} for v_i ≥ 6 \text{V}. The transfer characteristic is displayed in Fig. 2-34(a). For the given input signal, the output is a sine wave with the positive peak clipped at 6 \text{V}, as shown in Fig. 2-34(b).
