A power amplifier has a gain of 20 dB and an input level of 2 volts. Assuming that the input and output impedances are the same, what is the voltage level at the amplifier output? 10 V 20 V 30 V 40 V
Added by Jamie R.
Step 1
Gain in dB is given by the formula: \( G_{dB} = 20 \log_{10} \left(\frac{V_{out}}{V_{in}}\right) \), where \( V_{out} \) is the output voltage and \( V_{in} \) is the input voltage. Show more…

An amplifier with an input resistance of 5 k, when driven by a current source of 1 ÎĽA and a source resistance of 200 k, has a short-circuit output current of 5 mA and an open-circuit output voltage of 10 V. If the amplifier is used to drive a 2-k load, give the values of the voltage gain, current gain, and power gain expressed as ratios and in decibels.

Two amplifier are connected after the orher in series (cascaded). The first amplifier has a voltage gain of 10 and the second has a voltage gain of 20 . If the input signal is $0.01 \mathrm{~V}$, calculate the output AC signal. (a) $3.6 \mathrm{~V}$ (b) $4.2 \mathrm{~V}$ (c) $2.0 \mathrm{~V}$ (d) $5.2 \mathrm{~V}$
