A sensor is used to measure a physical variable and convert it into a variable electrical.

For this problem, assume a sensor is being used to measure flow of ethanol in a chemical reactor.

The sensor output signal is shown in Figure 8.

This signal is amplified using an amplifier whose input-output transfer curve is shown in Figure 9. a) Determine the gain of the amplifier. b) What happens if the input voltage of the amplifier is greater than 13.5 V? c) Obtain the graph of the amplifier output signal.

*I am asking for parts a, b & c. (Don't make only one and ignore the rest pls) Thanks!
