![]() The minimum analog signal amplitude that can bring about a change in the digital signal is called the Least Significant Bit (LSB), while the (rounding) error that occurs between the analog and digital signals is referred to as quantization error. With digital sampling comes quantization errors that create low-level noise which gets added to the reconstructed signal. A conventional D/A converter puts the numbers into a piecewise constant function made up of a sequence of rectangular functions that is modeled with the zero-order hold.Ī D/A converter reconstructs original signals so that its bandwidth meets certain requirements. ![]() ![]() D/A converters are often used to convert finite-precision time series data to a continually varying physical signal.Īn ideal D/A converter takes abstract numbers from a sequence of impulses that are then processed by using a form of interpolation to fill in data between impulses. Therefore, the whole range of analog voltage is required to be represented suitably in 2N intervals, and each of the intervals corresponds to a digital output. ![]() And it will produce the digital output of 2N number of discrete values for an N-bit converter. A D/A converter takes a precise number (most commonly a fixed-point binary number) and converts it into a physical quantity (example: voltage or pressure). Analog to Digital Converters - ADC Analog to Digital Converter. In an analog to digital converter, the input analog voltage may have any value in a range. ![]()
