A transmitter and receiver are connected using a cascaded pair of transmission lines. At the operating frequency, line 1 has a measured loss of 0.2 dB/m, and line 2 is rated at 0.3 dB/m. The link is composed of 30 m of line 1 joined to 20 m of line 2. At the joint, a splice loss of 2 dB is measured. If the transmitted power is 120 mW, what is the received power?

A transmitter and receiver are connected using a cascaded pair of transmission lines. At
the operating frequency, line 1 has a measured loss of 0.2 dB/m, and line 2 is rated at 0.3
dB/m. The link is composed of 30 m of line 1 joined to 20 m of line 2. At the joint, a
splice loss of 2 dB is measured. If the transmitted power is 120 mW, what is the received
power?
