1. a) Using the following table draw a sampled analog signal for digital signal representation. By applying the concept of Pulse Code Modulation find the [10] 4-bit code words and finally draw the digital signal by using MLT-3 line coding scheme. You have to solve the problem by using step by step formulation of normalized PAM values, normalized quantized value, normalized error and quantization code. Assume that the sampling amplitudes are between -40V to +40V. Time Analog Signal Value (V) 0 -24.7 1 15.7 2 28.6 3 -20.5 4 34.5 b) Find the digital data from the given analog signal using Delta Modulation (DM) technique. You can use any mean of your preference to show your work. You can even choose to draw the waveform in your script along with the grids [5] (15x15) and then perform the technique. Your waveform in that case should be roughly similar to the one given with respect to the size and shape. Page 3 of 5 delta
