Which of the following does not cause standing waves?(a) Short circuit

1.	Which of the following does not cause standing waves?(a) Short circuit(b) Open circuit(c) High frequency high power signal(d) Impedance is not matched
Answer» The correct option is (c) High frequency high power signal To elaborate: If the load at the end of a line is an open circuit or a short circuit or has an impedance other than the characteristic impedance of the line, the signal is not fully absorbed by the load. This causes the signal to get reflected back the line and cause a standing wave.
