In an unmatched line the actual signal on the line is ___________(a) T

1.	In an unmatched line the actual signal on the line is ___________(a) The sum of forward and reflected signals(b) The difference of forward and reflected signals(c) The product of forward and reflected signals(d) The modulus of forward signalI had been asked this question during an interview.Enquiry is from Standing Waves topic in division Transmission Lines of Avionics
Answer» The CORRECT CHOICE is (a) The sum of forward and reflected signals Easiest explanation: In an UNMATCHED line, standing WAVES are formed which is a combination of forward and reflected SIGNAL. The signal actually on a line is simply the algebraic sum of the forward and reflected signals.
