Extracted text: A function generator, whose output resistance is 210 2, is adjusted to produce an open-circuit sinusoidal output voltage of 0.7 Vp-p. This function generator is connected to an amplifier, which in turn drives a load resistor RL as shown. Amplifier The voltage drop appearing across the amplifier's input terminals is 0.508 Vp-p. Meanwhile, the voltage drop appearing across the load resistor is 63.48 Vp-p if RL = 40 N, but increases to 80.79 Vp-p if RL -70 Ω. Determine the amplifier's (a) input resistance R; Ω (b) output resistance R. Ω (c) open-circuit voltage gain A =
