The following sections of the e-book will give you all the information you need to answer all 4 questions: http://www.allaboutcircuits.com/vol_4/chpt_7/2.html http://www.allaboutcircuits.com/vol_4/chpt_7/3.html http://www.allaboutcircuits.com/vol_4/chpt_7/4.html http://www.allaboutcircuits.com/vol_4/chpt_7/5.html Have a read and then try the questions and post your answers up, we will be more than willing to provide help and direction, but you must do the work.
