The AC component superimposed over the DC output voltage. In linear power supplies, this is the traditional “hum†at 60 or 120 hertz. In switching power supplies, it is a complex waveform. Although traditionally specâ€(tm)d at 1%, it is often much lower. Ripple can increase at maximum loading and minimum input voltage.
The magnitude of a unit's output AC voltage.
(electronics) an oscillation of small amplitude imposed on top of a steady value
The deviation from a linear function or fundamental shape. This is usually applied to amplitude, phase, or group delay in filter terminology.
A power supply output voltage AC noise component that is periodic.
Ripple is the amount of fluctuation left over from the rectification of AC to DC. It is measured in volts peak to peak or volts RMS. Switching power supplies have high frequency ripple, linear power supplies have low frequency ripple (some multiple of 60 Hz).
The periodic noise component of the power output voltage. See PARD.
Amplitude variations in the output voltage of a power supply caused by insufficient filtering.
A measurement of the RMS value of A Ccomponents superimposed on a DC source.
Generally referring to the wavelike variations in the amplitude response of a filter. Chebychev and elliptic function filters ideally have equi-ripple characteristics, which means that the difference in peaks and valleys of the amplitude response in the passband, are always the same. Butterworth, Gaussian, and Bessel functions do not have any ripple. Ripple is usually measured in dB.
The difference between maximum and minimum attenuation in the passband.
The periodic AC component at the power source output harmonically related to source or switching frequencies. It is expressed in peak-to-peak or rms units over a specified band with. Related Terms: PARD (Periodic and Random Deviation) | Pi Filter | Post Regulation
Within a pass band, it is the difference between maximum and minimum attenuation
The small amount of a/c source residue that appears on the output of a d/c power supply. The smaller the ripple, the better the power supply. Applies to Tripp Lite PR series DC power supplies.
The residual ac left after rectification, filtration and regulation of the input power.
AC voltage superimposed onto the DC output, expressed as a percent of the normal output voltage or as peak to peak volts. A power supply with clean DC output is essential for computers with high-speed CPUs and memory.
distinguished from noise by its periodic non-random nature, ripple is characterized by a series of small ac voltage or current peaks on a dc signal; it is typically a by-product of converting ac to dc.
The ratio in percent between the residual AC voltage (ripple, peak to peak) on the DC voltage supply and the DC supply itself, that the sensor will operate on.
The vaiation in a dc voltage on the output of a filtered rectifier caused by the slight charging and discharging action of the filter capacitor.
Any deviation from flat response in a passband.
The maximum deviation from flat response, measured in decibels-it indicates the port's effect on woofer output.
