1. A continuous-spectrum baseband signal has a spectrum extending from 3 kHz to 8 kHz. It is applied as one input to an ideal balanced 
modulator. The carrier input is a sinusoid having a frequency of 100 kHz. (a) Determine the range of frequencies contained in the DSB 
output spectrum. (b) Determine the required transmission bandwidth for an AM modulated system. 
a. This spectrum ranges from 3-8kHz. fc = 100kHz 
Lowest frequency = 100kHz – 8kHz = 92kHz 
Highest frequency = 100kHz + 8kHz = 108...

1. Given that a repeater is 25 km from a transmitter sending data at a frequency of 
1800 MHz, what is the path loss between the transmitter and repeater? 
a. 125.5 dB b. 132.0 dB 
c. 130.5 dB d. None of these 
L 
dB=20∗log (f )+20∗log(d )−147.56 dB 
20∗log (1800∗106)+20log(25∗103)−147.56 dB ≈ 125.5 dB 
2. Short term fading is caused mainly by terrain configurations and the built 
environment. 
True False
