When are transmissionline effects important For which of the

When are transmission-line effects important? For which of the following situations must transmission-line effects be taken into account? Assume a sinusoidal wave traveling along the line at velocity c. A 60-Hz signal on an electric power line from Academy of the Pacific to Kahuku High School. A 1-cm interconnect between two GaAs digital chips mounted on a Teflon circuit board. For Teflon, the signal travels at 0.67c.

Solution

for the case(a) we have to consider the transmission line effect(distributed parameters,different voltage values at different locations at the same time,reflection and refraction of voltages) because these are depends upon the length of line.

for case(b) the capacitance effects are high compared to resistance and inductance parameters
