Question

You are required to create a function in matlab that implements an Analogue to Digital Converter (ADC). The principle of operation of the ADC would be the successive approximation method. Inputs of the function should be the input voltage Vin, the reference voltages Vmin, Vmax and the resolution Q of the ADC in use. The output should be the quantized voltage Vg, and the binary number N (in decimal form) of the ADC. For the values of Vmin = OV, Vmax = 5V, Q = 11bits, provide in a plot the input/output diagram of your converter.

Answer 1

To create an ADC using the successive approximation method in Matlab, define the necessary input arguments and use the iterative approximation process to calculate the quantized voltage and binary number. Generate a plot to show the input/output diagram of the converter.

Step-by-step explanation:

To create a function in Matlab that implements an ADC using the successive approximation method, you can start by defining the input arguments of the function as Vin (input voltage), Vmin (minimum reference voltage), Vmax (maximum reference voltage), and Q (resolution in bits). You can then calculate the quantized voltage Vg and the binary number N using the successive approximation method. The ADC will compare the input voltage to a series of reference voltages and iteratively approximate the input value until it converges to the closest digital representation.

In the case of Vmin = 0V, Vmax = 5V, and Q = 11 bits, you can generate a plot showing the input/output diagram of the converter. On the x-axis, you can represent the input voltage Vin, and on the y-axis, you can represent the quantized voltage Vg. The plot will show how the input voltage is quantized and represented digitally with a finite number of levels
