Procedure 1. To demonstrate a passive clipping circuit; connect the circuit in Figure 3. 2. With a dual trace oscilloscope set to dc output coupling , sketch the input vs and vl. Record the voltage level at which clipping occurs. Clipping occurs at 3.96V 3. Connect the circuit in Figure 4.. Clipping occurs at -3.96V
