What is a reference voltage of an adc?
The voltage at which the adc converts the signal.... it can also be called a limit of an ADC.
Comparison between ADC and DAC?
An ADC, or analog to digital decoder, is used to "translate" analog signals into digital signals. An analog signal can take on any value, such as 0.1V, 0.5V, 4.12V, 5V and so on. A digital signal on the other hand can either be "high" or "low", 1 or 0. A computer can only work with digital signals, and therefore you need to convert an analog signal into a digital signal in order for the computer to be able to work with it. This is what you do when you record sounds or music. Sound is an analog signal and had to be converted with an ADC to a digital signal before it can be used in a compter or stored on a CD. A DAC, or digital to analog decoder is the oposite of the ADC. Here the digital signal is converted into an analog signal. This is what happens when you play music from a CD-plate. On a CD there are a number of holes, which each translates as a 0 or 1. These are read with a laser beam which is reflected back into a receiver whenever the laserbeam hits a hole. This then counts as a 1. When the disk is spinning it produces a stream of 1s and 0s, which togerther form a binary string, such as 00010111011101. The DAC then converts this value into a analogue signal, such as 1.1V, which is then used to power your speaker and produce audible sound.
What converts a message from digital to analog and analog to digital?
An DAC convert digital signal to analog signal i.e Digital to Analog Converter. An ADC convert analog signal to digital signal i.e Analog to Digital Converter.
What are the types of ADC?
Types Of ADC Are As follows: 1.Counter type ADC 2.Successive approximation type ADC 3.Flash Type ADC 4.Wilkinson type ADC
What is monolithic ADC?
a monolithic ADC is an integrator-based analog-to-digital converter. Simply put, the input voltage signal is integrated, compared to a reference voltage, and converted into a digital representation. The integrator uses a reference capacitor (hence monolithic i imagine), which is chosen depending on the bandwidth of the input signal.Don't take my word for it, see for yourself. The ICL7135 for example is a monolithic ADC with 4 and 1/2 digits BCD output.
What is a reference voltage of an adc?
The voltage at which the adc converts the signal.... it can also be called a limit of an ADC.
What is Counter type ADC?
Counter type ADCOne of the simplest types of the ADC is the Counter type ADC. The input signal of the ADC is connected to the signal input of its internal comparator. ADC then systematically increases the voltage on the reference input of the comparator until the reference becomes larger than the signal & the comparator output goes to zero.Fig.1 Counter type ADCDinesh Kumar - http://harshit.org
Who created ADC?
ADC, or Analog Devices, Inc., was founded in 1965 by Ray Stata and Matthew Lorber. The company specializes in high-performance analog, mixed-signal, and digital signal processing (DSP) integrated circuits. ADC has played a significant role in the development of various electronic components and systems over the years.
Explain the purpose of the simple and hold circuit in a computer controlled data acquisition system that uses a ADC?
I presume you mean "sample and hold"; to read a voltage an ADC takes a finite amount of time - if the voltage changes during that time, then a misreading can occur. The sample and hold keeps the voltage seen by the ADC constant during the reading time.

What is adc resolution?
ADC resolution refers to the smallest change in an analog signal that can be represented by the digital output of an Analog-to-Digital Converter (ADC). It is typically expressed in bits; for example, a 12-bit ADC can represent 2^12 or 4096 discrete levels. Higher resolution allows for more precise measurements of the analog signal, as it can differentiate smaller changes in voltage. Essentially, the resolution determines the accuracy and detail of the digital representation of the analog input.
The current amplification factor adc is given by?
The current amplification factor, ADC, is calculated by dividing the output current by the input current in a circuit. It represents how much the current signal is amplified in the circuit. ADC can be expressed as the output current divided by the input current (ADC = I_out / I_in).
What chip converts sound waves from a voice into digital signal?
The chip that converts sound waves from a voice into a digital signal is typically called an analog-to-digital converter (ADC). In voice recognition devices, this process often begins with a microphone that captures sound waves, which are then transformed into an electrical signal. The ADC then digitizes this electrical signal, allowing it to be processed by a computer or digital device for further analysis or recognition.

Can portc of pic16f84a can be configured for analog signal inputs?
No, the PORTC of the PIC16F84A cannot be configured for analog signal inputs. The PIC16F84A features digital I/O ports, and while it has some capability for analog signals through the use of an external analog-to-digital converter (ADC), its PORTC pins are strictly digital. To handle analog signals, you would need to use an external ADC or a different PIC model that includes built-in ADC functionality.
What is quantization error of an ad converter?
Quantization error in an analog-to-digital converter (ADC) refers to the difference between the actual analog input signal and the quantized digital output value produced by the ADC. This error arises because the continuous range of the analog signal is mapped to discrete levels, leading to a loss of precision. The magnitude of quantization error is influenced by the resolution of the ADC; higher resolution reduces the error by allowing more discrete levels for representation. Ultimately, quantization error can introduce distortion and affect the overall accuracy of the digital signal.
