3) The large signal current voltage equations of a newly produced transistor (3 terminals) are given as follows. The following indices represent terminals. 12,3 = V; + 2V,+ 5V, eer V1 > 0.4 V 11 = 0 eerrif Using MATLAB, Microsoft Excel or a program with which you can draw a chart, plot the graph of function f(V1) = 12,3 for 0.4 V 0.4 V 11 = 0 eerrif Using MATLAB, Microsoft Excel or a program with which you can draw a chart, plot the graph of function f(V1) = 12,3 for 0.4 V
