22 maj 2022 · A certain system uses a 12-bit word to represent the input signal. If the maximum peak-to-peak signal is set for 2 V, determine the resolution of the system and its dynamic range. A 12-bit word means that \(2^{12}\), or 4096, levels are possible.

21 cze 2018 · With 12-bit resolution, $2^{12}= 4096$ different numbers can be represented, this means that the measuring range of a given sensor gets split into 4096 pieces. As an example, if your sensor can measure from 0V to 409.6V (just for nicer math), then with 12-bit resolution, you can resolve the measured value in increments of 0.1V.
21 gru 2022 · The resolution of a sampler is the number of bits that are used to represent each signal. For instance, a 12-bit sampler will output 12 bits of data for every sample. This means that there are 2 12 possible digital values that each sample can be converted to.
The resolution of an ADC is specified by the number of bits used to represent the analog value. Ideally, a 12-bit ADC will have an effective number of bits of almost 12. However, real signals have noise, and real circuits are imperfect and introduce additional noise and distortion.
We can use an 4-bit number (for example) to represent the points between "high" and "low". This would result in 16 possible (vertical) points - see the figure below. If we chose a 10-bit number, it would result in 1024 different possible points, and thereby a greater signal resolution.
29 sie 2024 · The Bit Resolution Calculator helps determine the precision of a digital system in representing an analog signal. Bit resolution is a critical factor in digital signal processing, analog-to-digital conversion, and digital system design.
23 maj 2024 · An 12-bit Analog-to-Digital Converter (ADC) is a device that converts analog signals into digital signals. The “12-bit” part refers to the resolution of the ADC, meaning it can produce 2 12 = 4096 discrete values.
