The main disadvantage of FIR filters is that considerably more computation power is required compared with a similar IIR filter.
The prover is all-powerful and possesses unlimited computational resources, but cannot be trusted, while the verifier has bounded computation power.
The assistance server has a good satellite signal, and plentiful computation power, so it can compare fragmentary signals relayed to it.
In practice although adiabatic circuits have been built, they have been difficult to use to reduce computation power substantially in practical circuits.
If such computers were realized, their computation power would be much greater than that of functioning, "implementable" computers.
Ironically, the reason they wanted to go to CompuServe was to have enough computation power to do Island of Kesmai, but it proved too computationally expensive.
The prover is modeled as having unlimited computation power (in practice, P usually is a Probabilistic Turing machine).
The advantage is that FFT and frequency domain equalization requires less computation power than the conventional time-domain equalization.
Networked throughout a system of millions of PCS, the CIA was able to add gigabytes of computation power to the problem.
The effort consumed the bulk of the ship's computation powers for twelve thousand years.
