Problem 1: BJT DC Circuits Analyze the four circuits below, first analytically and then verify using simulations in PSPICE/Multisim. You have to solve each circuit that is, find the status of the BUT (active, saturation or cutoff mode) and then find all the node voltages and all the currents. Whenever you solve manually always make the following assumptions: for npn BIT VE-0.7V (if the BE junction is forward biased) for pap BIT VEB-0.7V (if the BE junction is forward biased)...
