Minimum Detectable Signal Calculator

Minimum Detectable Signal Calculator calculator can be used to determine the smallest signal that can be detected given a specific Signal-to-Noise Ratio (SNR) and other parameters.

Input Parameters

Calculation Results

Calculation Formula

MDS = 10 * log10((SNR - 1) * Noise Power + Noise Power) + Bandwidth

Where:
MDS = Minimum Detectable Signal (dBm)
SNR = Signal-to-Noise Ratio (dB)
Noise Power = Noise Power (dBm)
Bandwidth = Bandwidth (Hz)

Learn how to use the Minimum Detectable Signal Calculator calculator and its working principles

How to Use the Calculator

  1. Enter the Signal-to-Noise Ratio (SNR) in dB. This is the ratio of the signal power to the noise power.
  2. Enter the Noise Power in dBm. This is the power of the noise.
  3. Enter the Bandwidth in Hz. This is the frequency range over which the signal is measured.
  4. Click the "Calculate" button to compute the Minimum Detectable Signal.
  5. The result will be displayed in dBm, which is the smallest signal that can be detected given the specified parameters.

Working Principle

The Minimum Detectable Signal (MDS) is the smallest signal that can be detected with a specified level of confidence. It is calculated based on the Signal-to-Noise Ratio (SNR), noise power, and bandwidth. The formula used is:

MDS = 10 * log10((SNR - 1) * Noise Power + Noise Power) + Bandwidth

This formula takes into account the noise power and the desired SNR to determine the smallest signal that can be detected.
