a) Convert the following bit stream to a signal using an appropriate encoding scheme that matches the requirements given. Write which signal encoding scheme you are using. Data: 1 0 1 0 110111000001 Requirements The encoding scheme must occupy a low bandwidth. Any self- synchronization and DC component problem may be ignored. Time 0 1 2 3 4 The encoding scheme must be self-synchronizing and should not have a DC component problem. High bandwidth is Acceptable. b) The following table depicts a sampled analog signal for digital signal representation. By applying the concept of Pulse Code Modulation, assume there will be 3-bit code words for each sampled amplitude. Show the normalized quantized value and quantization code for the given analog signal value at different time stamps. Assume that, the sampling amplitudes are between -40V to +40V. Analog Signal Value (V) 5.3 12.7 -6.8 -18.4 19.5
