ı just need fınal aswer In the circuit in the figure, Vcc = 18 V, Rs1 = 0.9 kΩ, Rs2 = 0.5 kΩ, R1 = 75 kΩ, R2 = 15 kΩ, RC = 2.2 kΩ, RE = 1 kΩ and β =120. It is also known that Cwi = 6 pF, Cwo = 10 pF, Cbc = Cu = 7 pF, Cbe = Cπ = 58 pF and Cce = 11 pF. Accordingly, considering the frequency response of the circuit, what would be the high cutoff frequency (fH)?
