29. For the two-stage, capacitively coupled amplifier in Figure 6-57, find the following values: (a) voltage gain of each stage (b) overall voltage gain (c) Express the gains found in (a) and (b) in dB. 30. If the multistage amplifier in Figure 6-57 is driven by a 75 2, 50 µ' stage is loaded with an R, = 18 k2, determine 341/992 (a) voltage gain of each stage (b) overall voltage gain (c) Express the gains found in (a) and (b) in dB. FIGURE 6-57 Vcc +15 V R1 R3 3.3 kn C. Rs 33 kN 33 k2 3.3 kn C5 C, 10 uF 10 µF V 10 µF R4 R2 8.2 kn C2 100 μF 1.0 kn 8.2 kn 1.0 kN Ba: = BDc = 175 31. Figure 6-58 shows a direct-coupled (that is, with no coupling capacitors between stages) two- stage amplifier. The de bias of the first stage sets the de bias of the second. Determine all de voltages for both stages and the overall ac voltage gain.
