hi all
according to pdf i've sent i have a problem with it
in page 11 the author uses -1v as a grid bias voltage
before he ploted the dc load line on the curve
of course we know that -1v means that -1 to zero for positive and -1 to -2 for negative cycle of swing
but in page 13 as u can see he used -1.5v as grid voltage in order to calculate the cathode resistor to plot ac load line
using -1.5 has a special reason or the authur prefered to use it??
and i wanna know that the way to achieve the optimum bias point is that we should plot ac and dc load line in triodes and the cross point of them is our optimum?
