Refer to Figure 2.2, calculate theoretically the lower and upper cut-off frequencies by assuming the approximated value of beta (B) = 300. For stray and transistor capacitances, you may use the approximated values. Vcc= 20V Rc1 kn Cc 4.7 kN R1 oVout C, 10 uF 2N3904 1 uF RL 1 kn 1 Vac 0 Vdc Vin R2 1 kn Cr RE 1 kn 22 uF States)
