A cable company provides a 0 dBmV signal at 843 MHz via a 75-2 coaxial cable to a cable modem which is located in a residence. This modem uses this downstream signal to produce the downloaded data signal for the Internet subscriber's computer via an ethernet connection. (The uplink signal that is sent by the modem is on 33.5 MHz.) What is the power of the 843 MHz signal that is supplied to the modem if the modem acts as a 75-22 resistive load to this downstream signal?
