Question

Consider a similar amplifier with a higher output resistance Rout = 150 ohms (it is no longer 75 ohms). This is illustrated in the diagram below. Again, assume input and output impedance matching. Vin = 0.4 volt Vout = 10 volts AMP Rin = 75 ? Rout = 150 ? (a) Write an expression for the power gain PG in decibels in terms of Vin, Vout and the ratio of Rin to Rout. Show your derivation step by step with assumptions made. (b) What is the power gain in decibels for the amplifier in the above figure using these values for the voltages and the resistances?

Step 1

First, let's find the output power Pout. The output power can be calculated using the formula Pout = (Vout^2) / Rout, where Vout is the output voltage and Rout is the output resistance. Pout = (10^2) / 150 = 100 / 150 = 0.6667 watts Show more…
