21. Which of the following is True about VSWR?

1. VSWR is defined as the ratio between maximum Characteristic Impedance and minimum Characteristic Impedance in a standing wave
2. VSWR is defined as the ratio between maximum impedance mismatch and minimum voltage in a standing wave
3. VSWR is defined as the ratio between the maximum voltage and minimum voltage in a standing wave
4. VSWR is defined as the ratio between the maximum voltage and minimum impedance mismatch in a standing wave

Answer: C) VSWR is defined as the ratio between the maximum voltage and minimum voltage in a standing wave.
