Abstract :
This paper describes the measurement of the time delay for a transmission line using a frequency discriminator to demodulate a carrier with FM modulation in frequency domain. The trace of demodulation signal shows the dip points. These dip points appear at the frequency multiples of 1/Td. The measurement results of the frequency domain are compared with the time domain method.
