The binary sequence 011010 is transmitted through a channel having a raised cosine characteristic with rolloff factor of unity. Assume the use of polar signaling, with symbols 1 and 0 represented by +1 and -1volt, respectively. i) Construct, to scale, the received wave, and indicate the best sampling times for regeneration. ii) Construct the eye pattern for this received wave and show that it is completely open. iii) Determine the zero crossings of the received wave.
