Calculate Signal to Noise Ratio (SNR) for various applications like audio, image processing, and telecommunications.
Signal to Noise Ratio (SNR) is a measure used in science and engineering to quantify the level of a desired signal relative to the level of background noise. It's a key metric in various fields including audio engineering, telecommunications, and image processing. SNR is usually expressed in decibels (dB).
The importance of SNR lies in its ability to indicate the clarity and quality of a signal. A higher SNR means a clearer signal with less noise, which is crucial for accurate data transmission and interpretation. In audio applications, for instance, a high SNR ensures that the sound is clear and free from unwanted background noise.
SNR is calculated using the formula: SNR (dB) = 10 * log10(P_signal / P_noise), where P_signal is the power of the signal and P_noise is the power of the noise. This calculator simplifies the process by allowing you to input the signal and noise values and instantly get the SNR in dB.
| Signal Power (W) | Noise Power (W) | SNR (dB) |
|---|---|---|
| 100 | 10 | 10 |
| 1000 | 1 | 30 |
