The following four output displays of an oscilloscope (right hand side, below) show waveforms of a biased diode ac circuit. An example is illustrated on the left hand side. VIN is the yellow waveform (10 Vp-p), VOUT is the blue-green (aqua) waveform (the red is VIN - VOUT but leave that aside). Consider three other possibilities regarding the orientation of the diode and DC bias voltage source VB and match the circuit configuration with display. State any assumptions you make about the diode.
a. Sketch the waveform at points A and B of the circuit shown below. Assume the diode is ideal. The excitation voltage VT is a ± 5volt square wave at a frequency of 500Hz and with a mark space ratio of 1. Give one possible application for this circuit.
b. Sketch the waveform at points A and B of the circuit shown in figure 1. Assume the diode is ideal. The excitation voltage VT = 20 sin100pt. Give one possible application for this circuit.
c. A diode has a saturation current in reverse bias of 10-13 A. Calculate the current at room temperature if a forward bias of 0.65V is applied
