In a broadcasting communication system, the transmitter power is 40 kW, the channel attenuation is 80 dB, and the noise power spectral density is 10^-10 W/Hz. The message signal has a bandwidth of 10⁴Hz.

1. Find the predetection SNR (SNR in r(t) = au(t) + n(t)).

2. Find the output SNR if the modulation is DSB.

3. Find the output SNR if the modulation is SSB.

4. Find the output SNR if the modulation is conventional AM with a modulatio index of 0.85 and has a normalized message power of 0.2.
