章节摘录
The nature of electrical signals in electronic circuits readily enables the technology tobe divided into classes. One of the classes is analog electronics, another: is digital electron-ics. Both analog and digital electronics use similar electronic elements, but the manner ofuse is different, and the technologies appear to be quite distinct. For this reason we shallstudy them separately until we bring them together as they invariably unite in instrumen-tation and applications. Analog electronics pertains to those systems in which the electrical voltage and elec-trical current are analogous to physical quantities and vary continuously. Electronic circuitsthat reproduce music must have voltages and currents that are proportional to the sound. Ahigh fidelity amplifying system attempts to keep the analogy as true as possible. Analog e-lectronic circuits are carefully designed to make the electrical voltages and currents followthe input signal. If an input signal doubles in amplitude, the output voltage or current alsoshould be double. This is possible because the circuit elements are made to operate withinlimits that preserve the linearity. An electrical voltage that is proportional to temperature and changes smoothly as thetemperature changes is an analog of temperature. If the temperature range is divided intosmall increments, however, and a numerical assignment is made to each increment, thenthe temperature may be indicated by a digital display. As the temperature (voltage) chan-ges smoothly, a decision must be made by an electronic system as to the numerical valueto be displayed as the temperature. The circuit making the decision is called an analog-to-digital converter, ADC. The inverse process is accomplished by a digital-to-analog con-verter, DAC. Digital electronic circuits do not require the linearity of analog circuits. Digital circuitsact as electronic switches and switch from one state to another. The output state, on oroff, is the only signal condition to be examined. In digital circuits the output state is deter-mined by the input signals in a manner as direct as the output voltage of an analog circuit isrelated to the input signal. In digital circuits the relation between input and output statesare expressed as logic equations, and the elements of digital electronics are called logicgates. Logic gates switch between states, on or off, very quickly so that they may operateat many megahertz in computers and other applications.
