mVdecade

mVdecade refers to a unit of measure commonly used in electronics, particularly in contexts involving signal amplification or attenuation. It represents the change in voltage over a logarithmic scale, specifically a factor of ten. The "mV" signifies millivolts, a unit of electrical potential difference. The "decade" part indicates a tenfold increase or decrease.

Therefore, a change of one mVdecade means that for every tenfold increase in a parameter (such as frequency or input signal strength), the output voltage changes by one millivolt. Conversely, a tenfold decrease in the parameter would result in a one millivolt decrease in the output. This unit is often used when describing the gain or loss of circuits, particularly in radio frequency (RF) and audio engineering, where logarithmic relationships are prevalent. Understanding mVdecade allows engineers to quantify how a system's output responds to changes that occur across multiple orders of magnitude. It provides a consistent way to express the performance of components or systems that exhibit logarithmic behavior.
