I found this place on google and thought this forum might be able to help me understand my homework.

We are 4 students who are studying abroad at San Diego State University and we need help to understand a simple

problem in our homework. Aparently language is a barrier for us after all, hehe.

The problem sound like this:

*2.1 An amplifier with 40 dB of small-signal, open-circuit voltage gain, an input resistance of 1 MΩ, and an output resistance of 10 Ω, drives a load of 100 Ω.*

(a) What voltage and power gains (expressed in dB) would you expect with the load connected?

(b) If the amplifier has a peak output-current limitation of 100 mA, what is the rms value of the largest sine-wave input for which an undistorted output is possible?

(c) What is the corresponding output power available?

(c) What is the corresponding output power available?

There are no drawings or anything included in the paper what so ever.

We've are really confused as to what resistor is where. Is the input resistance the internal resistance? is there any feedback loop?

We really appriciate your help!
