Frequency and phase of a signal

Question

Question 1: Illustrate what does the amplitude, frequency and the phase of a signal measure?

Question 2: What are the basic differences between a simple periodic signal and a composite periodic signal?

Question 3: Determine the bit rate and what is its counterpart in the analog signal?

Question 4: Explain the frequency of a period of 220ns in Hz, kHz, and MHz?

Question 5: Determine the phase shift for a sine wave with maximum amplitude after 3/4 cycles?

Question 6: Find out the bandwidth of a signal which can be decomposed into four sine waves with frequencies at 0 Hz, 20 Hz, 50 Hz and 200 Hz? All maximum amplitudes are the similar. Also draw the frequency spectrum.

Question 7: Can we relate the negation of a signal to the phase shift? How many degrees?

Question 8: Draw the time domain representation of the signal illustrated below:

Question 9: Two signals have similar frequencies. Though, whenever the first signal is at the maximum amplitude, the second signal has amplitude of zero. Determine the phase shift between the two signals?

Question 10: Define the bit interval and bit rate.
