current amplification

current amplification

[′kər·ənt am·plə·fə′kā·shən]
(electronics)
The ratio of output-signal current to input-signal current for an electron tube, transistor, or magnetic amplifier, the multiplier section of a multiplier phototube, or any other amplifying device; often expressed in decibels by multiplying the common logarithm of the ratio by 20.

In comparison to the current amplification standard, polymerase chain reaction (PCR), RAM is more sensitive, rapid, cost-effective, and user- friendly.
The technique avoids the problems associated with current amplification methods, including contamination from previously amplified DNA.
Raman amplification boosts the strength of communications signals traveling through optical fiber more effectively than current amplification techniques, thereby allowing longer distances between amplifying devices.
