For amplifier signal-to-noise ratio, you measure the noise in the relevant bandwidth (probably 20 kHz for an audio amplifier) and compare it to the maximum amplifier output or to the typical amplifier output, as required.

Noise is one of the most important performance figures and typically given as SNR, Signal-to-Noise Ratio. This is a ratio of two separate measurements: high/maximum signal level and noise level without signal. In audio measurements, signals and noise are typically expressed in level instead of power. Thus, SNR(dB) = 20*log10(signal_level/noise_level).

The definition of SNR in dB is as follows: SNR = P signal / P noise; SNR is the signal to noise ratio in decibels [dB] P signal is the useful signal strength in watt [W] P noise is the noise power in watts [W] The causes of noise. In our audio frame, we come across this noise all the time, impossible to separate from it.

This magnitude of noise can be expressed by the so-called noise factor (F), which is the result of dividing the signal-to-noise ratio at the input (S / R) by the signal-to-noise ratio at the output (S / R ) salt, when the signal and noise values are expressed in simple values. The formula would therefore be expressed as follows:

Signal to Noise Ratio - This is a measurement of importance to consider as it is a ratio of the magnitude of the signal and background noise. Many amplifier manufacturers publish their SNR figures at full power, which can be misleading and hard to compare between different amplifiers at differently rated power levels.
