60 V D1 D2 2 kohm D4 D3 -60 V Assume that an input signal is applied to the circuit given above, as shown in the figure next to it. Accordingly, answer the following questions. The diodes used are silicon diodes, their operating voltages are 0.7 volts, and can be omitted because their resistance is very small. Write the name of this circuit, thinking about which circuit we do in the courses is equivalent to the purpose.

Question 2 If Vcc=9V, R1=R2%3D1,432 ohms, Beta=150, re'=9ohms, RL=474 ohms assume D1 and D2 are practical diodes. Compute the input resistance in ohms unit +Vcc R1 C3 D1 D2 C2 RL V R2

Calculate the equivalent resistances Rin of the following circuits. (The resistance value of the diodes in the conduction will be 0, the resistance value of the diodes in the insulation will be taken as infinity. R1=10ohm
