![]() Consider an entire system that collects data, not just the ADC. ![]() System has no actuator because it simply measures the measurand in Measurand in the real world to a desired value while the data x(t) is the time-varying signal we are attempting to measure. Figure 14.1 shows the data flow graph for a data Like sound, distance, temperature, force, mass, pressure, flow, lightĪcceleration. To measure distance to an object (EE319K skips this). Use the Central Limit Theorem to improve signal to noise ratio.Theorem to cases where we use the ADC to sense information. Quantization, range, precision and resolution. Transducers: conversion of physical to electrical.ĭigital computer to sense its analog world. We define the rate at which we sample as the sampling rate, and use the symbol fs.ĪDC, software, PWM output and motor interfaces to implement intelligent Interrupts to sample the ADC at a fixed rate. More specifically, we present a technique for theĪnalog inputs using an analog to digital converter (ADC). ![]() This chapter we will focus on input devices that we use to gatherĪbout the world. System uses its input/output devices to interact with the external Throughout this course we have seen that an Modified to be compatible with EE319K Lab 8 14: Analog to Digital Conversion, Data Acquisition and Control
