State whether the following statements are true or false:
(a) The purpose of a transistor amplifier is to enhance the frequency of the input signal.
(b) The gain of an amplifier is the ratio of the output signal amplitude to the input signal amplitude.
(c) The output characteristics of a transistor relate the collector current to the base current.
(d) If the load resistor value is increased the load line gradient is decreased.
(e) In a common-emitter amplifier, the output voltage is shifted by 180? with reference to the input voltage.
(f ) In a common-emitter amplifier, the input and output currents are in phase.
(g) The dynamic current gain of a transistor is always greater than the static current gain
