Especially I could not the find the low cut off frequency of the amplifier (fLs, fLc and fLe) partc
Solve clearly, I will give a thumbsup.
Following AC coupled voltage divider amplifier will be used to explore the frequency response of the common-emitter amplifier topology. Since the circuit has a rather high gain, a resistor divider network is included at the input of the circuit to keep the input signal small. 2N2222 transistor will be used in this experiment. +10 V 2.2 ΚΩ in TPF VE 10 ΚΩ IF tho 01 100 0 10 KO 1ΚΩ 10 uF 1 a. Find the value of resistance Roi that will bias the device at a collector voltage of Vc6-7 V. Make sure that you have selected a standard resistor value. Then calculate VCEQ, JEQ and re. b. Calculate the mid-band gain of the amplifier Avo = Vout/Vin, both as a ratio and in db. c. Determine the overall low cut-off frequency of the amplifier Plot the overall frau
