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 R as shown. Amplifier The voltage drop appearing across the amplifier's input terminals is 0.508 V,-p. Meanwhile, the voltage drop appearing across the load resistor is 63.48 V,-, if R = 40 2, but increases to 80.79 Vn-p if R = 70 2. Determine the amplifier's (a) input resistance R; = O.
