Question
In the circuit in the figure, Rs = 3.8 kΩ, R1 = 82 kΩ, R2 = 22 kΩ, RC = 5.6 kΩ, RE = 1.5 kΩ and RL = 3.3 kΩ and β = 150. Given that the capacitances are C1 = 0.5 μF and C2 = 0.09 μF, what is the low cutoff frequency of the given circuit?
NOTE-1: In the middle band frequency, β = 150 will be taken and the frequency dependence of β will not be taken into account.
NOTE-2: The output impedance of the transistor r0 will be neglected in the calculations.
