What is the voltage drop across the VBE of the transistor? Is the transistor switched on? [1 mark] 2. What is the voltage drop across the diode? Is the diode conducting? [1 mark] 3. Using your answers from the above questions, at what voltage will the transistor and diode switch on. Run a DC sweep for Vpot to get this answer. [1 mark] 4. You are required to do an analysis on this circuit. Use your simulation results and appropriate graphs for your analysis. Focus on the following: [6 marks] Is the above circuit in analogue or digital operation? • What voltage needs to be overcome for the diode D1 to turn on?
