About this webinar

Signal-to-Noise Ratio (SNR) is a statistical figure of merit used to measure the performance of a detector. It is a simple calculation that can compare various detectors to help you choose the right one for your application. Stochastic simulation of detector performance allows for a deeper analysis of the subtle contributions of detector characteristics such as gain, sensitivity, and noise to the SNR in various conditions.

This webinar will review the basics of signal-to-noise ratio calculation, the differences and similarities between different equations for SNR. It will discuss the factors that affect SNR, the sources of noise, and understand how the applications’ conditions determine the key detector characteristics. It will also examine some techniques to reduce noise, and further increase SNR.

Topics of presentation:

  1. Understand the signal-to-noise ratio calculation
  2. Understand how detector and amplifier gain impacts SNR
  3. Learn the factors that affect SNR
  4. Learn how to determine the dominant noise source
  5. Become familiar with using SNR to determine detector selection
