Aprašymas

What are the important characteristics of a A/D converters in data acquisition. What is an "op amp" and what is it used for. What is the resolution of a 12 bit A/D converter expressed as a percentage. What limits the accuracy of a 12 bit A/D card. What is the typical throughput rate of a fast PC based data acquisition board using DMA. Why signal conditioning is necessary and which features of system it improves. What elements are needed in PC-based DAQ measurement system. What is dynamic range of real world signals that come from transducers. List the types of common (typical) sensors (transducers). What is a thermocouple? What is level of signal (amplitude) in thermocouple outputs. Draw a structure of multi-channel DAQ. What is the difference between DAQ cards with and without bus mastering. What is the resolution of a 12 bit A/D converter expressed as a percentage. What is the typical throughput rate of a fast PC based data acquisition board using DMA. What is the definition of "real time". What is a more practical sampling frequency than that specified by the Nyquist frequency. What is "aliasing" and "anti-aliasing". What certain specific facilities should provide an ideal DAQ system. How it is possible to avoid noise in transmission cables from sensors to the DAQ. What is Fourier transform. How fast can an A/D read a varying input without a sample and hold. What sampling frequency does the sampling theorem indicate we need to sample a particular signal accurately. What is "interpolation" and when do we use it. What certain specific facilities should provide an ideal DAQ system. How it is possible to avoid noise in transmission cables from sensors to the DAQ. Can information be lost (or be wrong) in sampling process? Why. How the resolution is defined. Is it introduces additional distortion of data. How fast can an A/D read a varying input without a sample and hold. Characteristics of and use of analog-to-digital converters. What are the important characteristics of a D/A converters in data acquisition. What is quantization, sampling (discretization). What does term "dynamic range of signal" mean. Do digital systems have a noise? Why. Does analog systems have inherent system noises? Why. What is quantization error. How does typical ADC work. What input/output signals are needed for ADC functioning. The main technical parameters (characteristics) of DAC. What the sampling frequency is suitable for these signals. What is signal bandwidth? What is the telephone channel bandwidth. Intel 8255 PPI (programmable peripheral interface): structure, characteristics, implementation, programing. How does parallel (LPT) and serial ports (COM) work.
