Examples of ppm in a sentence

  • Georghiades [43] has compared the capacity, cutoff rate and error probability of on-off keying, PPM, overlapping PPM, and “combinatorial” PPM.The martingale techniques used in filtering problems proved successful in the derivation of the Shannon capac- ity of the Poisson channel without the PPM constraint.

  • Pierce argued that the ca- pacity of the PPM channel is equal to hf/kT nats per photon, where h and k are Planck’s and Boltzmann con- stants, resp., f is the center frequency and T is the noise temperature.

  • In our published decision on the claims true-up process17 we explained that we will expect any claim for traditional Prepayment Meter (PPM) credit balances to be based on thepercentage of the SoLR’s portfolio of smart PPMs with a credit balance on the day of customer transfer, and the average credit balance of those customers at midnight on the day of customer transfer.

  • This includes £700,744.74 in PPM balances, using the above methodology.

  • If a SoLR has provided evidence that characteristics of its customer base impacts upon the claim it submits for traditional PPM credit balances, Ofgem has taken this into consideration when assessing the claim’s underlying calculations.
