4. The transfer characteristics of a voltage amplifier are described by the graph below. Between points A and B, the amplifier gain is -50 V/V. The amplifier drives a load resistance of 1000 Ohms. VOUT Find the value of L in the graph (in V). a) 0 b)-8 c) -2 A(0.9V,2V) B(1.1V,L) VIN d) -6 e) -4 5. Find the maximum amplitude (in mV) for a sinusoidal input signal to avoid distortion at the output when a DC bias of 1.065V is added to the input sine wave. a) 85 b) 65 c) 35 d) 95 e) 80 6. Find the output power dissipated in the load (in mW) when the input voltage is a square wave with a low level of 0.9 V for 50% of the time and a high level of 1 V for the other 50% of the time. a) 2.0 c) 4.0 b) 2.5 d) 3.3 e) 6.5
