Dynamic Range Calculator:
Enter the values of maximum signal, MS and minimum detectable noise, DN to determine the value of Dynamic Range, DNR(dB).
Dynamic Range Formula:
Dynamic Range (DNR) is a measure of the range of intensities or amplitudes that a system can process or capture. It is commonly used in fields like audio, photography, signal processing, and imaging systems.
DNR indicates the ratio between the smallest and largest possible values a system can handle, ensuring that both very quiet and very loud signals can be captured without distortion or loss of information. A higher DNR implies better performance, as the system can process a wider range of signal strengths.
In digital imaging or photography, it measures the contrast between the brightest and darkest elements in an image. A higher DNR in cameras means more detail in both highlights and shadows.
Similarly, in audio, a high DNR ensures that subtle sounds can be captured without interference from louder sounds. The unit of DNR is typically expressed in decibels (dB), and it can be calculated using various formulas depending on the context.
Dynamic Range, DNR(dB) in decibel is the ratio of the maximum signal, MS to the minimum detectable noise, DN in a system.
Dynamic Range, DNR(dB) = 10 * log10 (MS / DN)
DNR(dB) = dynamic range in decibel, dB.
MS = maximum signal.
DN = minimum detectable noise.
Dynamic Range Calculation:
- Given: MS = 1000, DN = 1.
Dynamic Range, DNR(dB) = 10 * log10 (MS / DN)
DNR(dB) = 10 * log10 (1000 / 1)
DNR(dB) = 10 * log10 (1000)
DNR(dB) = 10 * 3
DNR(dB) = 30dB.
- Given: DNR(dB) = 40dB, DN = 2.
Dynamic Range, DNR(dB) = 10 * log10 (MS / DN)
40 = 10 * log10 (MS / 2)
4 = log10 (MS / 2)
104 = MS / 2
MS = 2 * 104
MS = 2000units.
