3. Consider the case of a ribbon cable constructed of 24-gauge wires separated a distance of 60 mils. Suppose the length of the wires is 0.5 m and that they are carrying a 30 MHz current. The level of current that will give a radiated emission in the plane of the wires and broadside to the cable (worst case) that just equals the FCC Class A limit (0.5 mV/m at 30 MHz, at a distance d=2.5m). (1) If the current is differential-mode current, how much is the differential-mode current it can carry? (2) If the current is common-mode current, how much is the common-mode current it can carry?
