The computational speeds and power efficiency of analog compared to digital have been promising for a long time. Historically, there has been a number of hurdles to developing analog systems, including the size and cost of analog processors.
For computer input devices, such asteletypewriters, to communicate with computer systems, they had to connect to a modem that linked to the front end of a computer system, such as a mainframe. Modem transmission speeds were slow compared with today's ultrahigh-speed networks. A fast modem in...

The advantages of digital signals as compared to analog signals are: Digital circuits are easier to design than analog signals Distortion, interference and noise do not affect these signals as compared to analog signals Configuration of digital signals is easier than analog The possibility of errors ...
Q.The quantization step size is calculated as Q=R/2N ,where R is the full scale range of the analog signal and N is the number of bits used by the converter .The strength of the signal compared to that of the quantization errors is measured by dynamic range and signal-to-noise ratio...
Answer:Analog signals when compared to digital signals are more accurate. Digital signals are less expensive, negligible distortion, and have a faster rate of transmission. Q #7) Why did we switch from analog-to-digital? Answer:Digital signals gave better quality and are less expensive when comp...
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 to an ...
Analog-to-digital converter A device for converting the information contained in the value or magnitude of some characteristic of an input signal, compared to a standard or reference, to information in the form of discrete states of a signal, usually with numerical values assigned to the various...
CONSTITUTION:An analog output value generating means 102 generates the result which is obtained by subtracting an offset quantity from the doubled value of the analog input value as an analog output value when the analog input value compared by a comparing means 101 is <=1/2 as large as a ...
It is characterized by its conversion rate, which determines the speed at which it converts analog values, and its resolution, which determines the accuracy of the digital representation compared to the original analog signal. The output of an ADC is a binary number that can be further ...
