AMicroprocessor Memory Bus: A microprocessor is clocked at afrequency of 3.75 GHz when communicating with memory on a printedcircuit board (PCB). A 15 cm long transmission line fabricated on asubstrate with relative permeativity Er = 4.4 connects the twocomponents. The transmission line has a characteristic impedance of50 Ohms. (A) Calculate the velocity of the signal through the wire.(B) If we want to read data from the memory, we will have to send asignal from the processor to the memory and then receive a signalfrom the memory. How long will it take to complete this process?(C) How many clock cycles will it take to complete a memory read?(D) Should we terminate (impedance match) either end of thetransmission line? If so, at which ends and why?
