Definitions for "Output Noise"
Keywords:  rms, noise, measurand, pwm, spl
The differential-mode output ripple and noise as measured with a 20 MHz bandwidth.
The amount of residual noise (dB SPL) generated by the electronics of a con-denser microphone.
The AC component that may be present on the DC output of a power supply. Switch-mode power supply output noise has two components: a lower frequency component at the switching frequency of the converter and a high frequency component due to fast edges of the converter switching transitions. Noise should always be measured directly at the output terminals with a scope probe having an extremely short grounding lead.
