Definition of "Dynamic Range" |
The range, in dB, between the noise floor of a device and its defined maximum output level. / The difference between the maximum over-load signal and the minimum acceptable signal in a system. In a system or device, the ratio of a specified maximum level of a parameter, such as power, current, voltage, or frequency to the minimum detectable value of that parameter. / Dynamic Range is the ratio between the largest and smallest possible values of a changeable quantity, such as in signals like sound and light. It is measured as a ratio, or as a base-10 decibel or base-2 doublings, bits or stops logarithmic value. / The ratio of the maximum output signal to the smallest output signal that can be processed in a system, usually expressed logarithmically in dB. Dynamic range can be specified in terms of harmonic distortion, signal to noise ration, or other performance criteria. / An armature winding in which the coils are laid in two layers and follow each other on the surface of the armature in the form of waves with the coils being so connected in series that there are only two paths for the flow of current whatever the number of poles in the machine . / refers to the range of input signal amplitudes over which an electronic device will operate within a set of specified parameters. Usually expressed in decibels. In a communications receiver, the upper end of the dynamic range is determined by the largest tolerable input signal, while the lower end is set by the receiver’s sensitivity. The sensitivity is the minimum discernible signal for a specific signal-to-noise ratio (SNR). |
