Some articles on rejection ratio, ratio:
... In electronics, power supply rejection ratio or PSRR is a term widely used in the electronic amplifier (especially operational amplifier) or voltage regulator ... The PSRR is defined as the ratio of the change in supply voltage to the equivalent (differential) input voltage it produces in the op-amp, often expressed in decibels ... at various frequencies (in which case the ratio is one of RMS amplitudes of sinewaves present at a power supply compared with the output, with gain taken into account) ...
Famous quotes containing the words ratio and/or rejection:
“Personal rights, universally the same, demand a government framed on the ratio of the census: property demands a government framed on the ratio of owners and of owning.”
