Quantization is done by replacing each value of an analog signal x(t) by the value of the nearest quantization level. To exemplify this operation, let's simulate a unipolar ADC (Analog to Digital Converter) having the technical specifications: R=10 Volts (full-scale range) and B=3 (number of bits). (a) Write a function y= adc_md1 (x,R,B) where x and y are vectors containing the input signal and the quantized signal, respectively; (b) Test your function with an input ramp signal ranging from 5 to 15 Volts (1 volt per step); and (c) On the same graph, use the plot and stem functions to display the input signal and the quantized signal
