output into a digital input for a computer or digital storage device. An ADC operates by periodically querying the output voltage of am instrument, converting the numeric voltage level to its binary equivalent and then presenting this binary equivalent as output. The ADCs output is then connected ...

analog-to-digital converter n.Abbr.ADC An electronic device that takes an electrical signal as an input, and yields a digital output signal representing the strength of the source signal, commonly used for recording digital audio. Also calledA/D converter. ...
图1是PWM-DAC的系统整体信号处理框图,包括PWM输出模块、RC低通滤波模块、驱动放大。其中PWM输出模块由微处理器通过软件编程来实现占空比可调的PWM波,在系统电源电压确定的情况下(5V/3.3V),PWM波的占空比决定着DAC电压输出的大小。RC低通滤波模块滤除PWM波的谐波分量,抑制输出电压的纹波。驱动放大模块采用运算放大器设计...
The answer lies in the history of analog to digital converters. Communication. This human imperative was the impetus behind the invention of the analog-to-digital converter (ADC). In fact, nearly all of the technological innovations that led to the ADC are the result of engineers and ...
inputs of the first and second lower bit encoder to respective resistors in the associated group of the resistor, and a circuit for alternately combining the m upper bits with the n lower bits generated by the first and second lower bit encoders and for generating the digital output voltage ...
the same number of bits per source output. The idea of vector quantization is to take blocks of source outputs of length n and design the quantizer in the n-dimensional Euclidean space rather than doing the quantization based on single samples inonedimensional space. ...
This output can then be processed and interpreted by a digital circuit (typically a microprocessor system). A digital-to-analog (D/A) converter, on the other hand, is used to convert the dig- ital output from a microprocessor or other digital device into an equivalent analog signal. The ...
