In a DSB-LC system, the message signal is 15 cos (87T*10*t) and the modulation index is 0.8. The antenna is represented as a 75 2 resistance. The equivalent noise spectral density at the receiver input is 2*1014 watt/Hz (double-sided). If the received signal power is 7*103 watt and the input noise power is considered in the entire signal bandwidth, find: 1- Path losses in dB. 2- SNR at the receiver output in dB.
