Dynamic range

from Wikipedia, the free encyclopedia

The modulation range or modulation range is the range of instantaneous values that the input variable of an arrangement has or may have if the specified conditions are complied with.

The typical case concerns the modulation of a low-frequency amplifier, which results in unpleasant distortions ( overload ) when the signals are too large . So this is about the linearity of the transfer characteristic .

Exceeding the permissible modulation range can also lead to the destruction of a component (e.g. loudspeaker, "breakdown" of a rectifier diode or a capacitor ).

If the specified conditions do not result from the context, they must be stated.

The value range of the size is usually adapted to the modulation range by adding a constant value (constant component ). In the case of a tube amplifier , for example, this is the grid bias .

With the Schmitt trigger , the limited control range of an amplifier is used to derive a discrete-value signal from an analog signal.
