CONFIDENTIAL BEE/BEP/181911/BEE2233 (b) The amplifiers in Figure 3 are cascaded and connected to a source and a load as shown in Figure 4. (1) Calculate the loaded midband gain for the Amplifier B, Amid (ii) Determine all the low cut-off frequency components for the Amplifier B. (iii) Decide which value contributes to the low cut-off frequency for the Amplifier B. (iv) Draw the asymptotes of the Bode plot for the amplifier using the results of part (iii). Then, draw the low frequency response curve in the same graph paper. Use the attached semi log graph in APPENDIX IV for your answer.
