Decomposing periodic analog signal into two sine waves having a phase shift equivalent to 1/6 and 1/8 cycle with respect to time 0. These sine waves have 8 and 12 cycles for a duration of one second. Both have a maximum amplitude of 15 volts. What are the phases in degrees and radians and represent both signals in time and frequency domains plot?

Q4:

What is the transmission impairment? List the common causes of impairment and explain each?
