WebADC and Sampling This is lab 3 of 10 in the course In this lab students will learn how analog signals from sensors are converted into digital signals using analog-to-digital conversion (ADC). Students will also learn about elements of ADC, such as sampling and Nyquist frequency. WebSuccessive Approximation Block Diagram The SAR starts by forcing the MSB (Most Significant bit) high (for example in an 8 bit ADC it becomes 1000 0000), the DAC converts it to VAREF/2. The analog comparator compares the input voltage with VAREF/2.
