In some types of communication systems binary data are transmitted using a technique called binary phase-shift keying (BPSK) in which a “1” is represented by a “burst” of a continuous-time sine wave and a “0” is represented by a burst which is the exact negative of the burst that represents a “1.” Let the sine frequency be 1 MHz and let the burst width be 10 periods of the sine wave.  Find and graph the CTFS harmonic function for a periodic binary signal consisting of alternating “1’s” and “0’s” using its fundamental period as the representation time.
