a) Design an AB-class sound amplifier according to the following criteria and draw the circuit diagram and give the values of all circuit elements. -Supply voltages will be taken 10 V. -Two 4 Ohm speakers will be connected to the output in series. -The biasing (ie bias) circuit will be designed with the VBE multiplier circuit (Is = 10^-13 A). -Total output power will be 5 Watt. -It is desirable that the calm current is 2 mA. B(Beta) = 100 for output transistors to be used. b) Calculate the efficiency of the designed circuit. c) In the designed circuit; Draw the collector current, VEC voltage and power consumption in the pnp transistor (give the values of the important points).
