Right Answer: A transfer curve is a graphical representation that shows the relationship between the input and output of a system, typically illustrating how the output changes in response to varying input levels in RF engineering and other fields.
Right Answer: The decibel (dB) is a logarithmic unit used to express the ratio of two values, commonly power or intensity. A change of 3 dB represents a doubling or halving of power, while a change of 10 dB represents a tenfold increase or decrease in power.
Right Answer: Gain is a measure of how much an amplifier increases the power, voltage, or current of a signal, expressed as a ratio or in decibels (dB).
Right Answer: A simple circuit to divide the frequency of a clock cycle by two is a D flip-flop. Connect the clock signal to the clock input of the D flip-flop, and connect the Q output back to the D input. The output Q will produce a clock signal that is half the frequency of the input clock.
