Tīmeklis2024. gada 5. apr. · But these different forms of expression are essentially the same —percentages and ratios (dB) are different ways of expressing the same thing. Recall the standard definition of decibels, or dB: dB = 20log 10 (V 1 /V 2) Where, V 1 and V 2 are the voltage (amplitudes) of the signals being compared. Tīmeklisas factor ( ratio) to the level in decibels (dB) Gain is the ratio between the magnitude of output and input signals. Gain controls on an amplifier are basically just small potentiometers (variable resistors) or volume controls, that allow you to adjust the incoming signal to the amplifier.
