Study and to explain the functioning of the editing. Propose the values of the resistances to obtain IC1, IC2 ~ 1mA and a total earning in tension ( two floors) > 100. Study the polarization of every constituent transistor. Determine the earning in tension, impedance of entrance and the impedance of exit to AC LF.

Study and explain operation of the following circuit. Calculate values of Rc1 and Rc2 to obtain collector currents of approx. 1ma each, with a total voltage gain for both stages of at least 100. Note polarity of signals at both transistors. Calculate input impedance, actual voltage gain, and output impedance to AC LF (don't know).

That's my translation...
