Signals and decibels

Levels, gain, noise and the several different things people mean when they say "dB".

These calculators are in development. Below is what is being built for this category.

Coming next

  • dB, dBm, dBV, dBu and dBSPL, converted in every directionsoon
  • Amplifier gain in dB and as a plain ratio, voltage and powersoon
  • Op-amp gain-setting resistors for inverting and non-inverting stagessoon
  • Thermal noise voltage from resistance, bandwidth and temperaturesoon
  • Signal-to-noise ratio and effective number of bitssoon
  • ADC resolution, LSB size and quantisation errorsoon
  • Sampling rate, Nyquist limit and aliased frequencysoon
