Heres one reason IOTA might do great in 2018 Consider a simple op-amp based headphone amplifier, like the CMoy pocket amplifier. This circuit has a single op-amp per channel doing the amplification. Noise and ripple (N+R) on the power supply affects an op-amp's output, so op-amp manufacturers publish Power Supply Rejection Ratio (PSRR) ratings for their chips. ripple cover 3 Sep 2015 Although this quantity is referred to as PSRR and input voltage ripple rejection, the terms mean exactly the same thing. The ripple rejection ratio is commonly expressed as dB. A ratio of 60 dB, for example, means that the input ripple is reduced to a 1/1000 factor. A 100 mV ripple is reduced to 0.1 mV.
