1. In a communication system, noise is most likely to affect the signal
a. at the transmitter
b. in the channel
c. in the information source
d. at the destination
2. Indicate the false statement. Fourier analysis shows that the saw tooth wave consist of
a. fundamental and sub harmonic sine waves
b. a fundamental sine wave and an infinite number of harmonics
c. fundamental and harmonic sine waves whose amplitude decreases with the harmonic number
d. sinusoidal voltages, some of which are small enough to ignore in practice
