If an alpha channel is used in an image, it is common to also multiply the color by the alpha value, to save on additional multiplications during compositing.

If the depletion region expands to completely close the channel, the resistance of the channel from source to drain becomes large, and the FET is effectively turned off like a switch.

If drain-to-source voltage is increased, this creates a significant asymmetrical change in the shape of the channel due to a gradient of voltage potential from source to drain.

If drain-to-source voltage is increased further, the pinch-off point of the channel begins to move away from the drain towards the source.

If both channels were created at the same time, all user statuses are retained when the two are combined ; if one is newer than the other, special statuses are removed from those in the newer channel.

If an event is sent on two channels at once, the event on the higher-numbered channel cannot transmit until the first one is finished, and so is delayed by 1ms.

If countN reaches 100, reads from the corresponding channel will be disabled.

## If so, send F backwards in time on channel c.

## If not, send F + 1 backwards in time on channel c. Note that this results in a paradox, as the number received in step 3 above is not the same as that sent in this step.

If N bits are conveyed per symbol, and the gross bit rate is R, inclusive of channel coding overhead, the symbol rate f < sub > s </ sub > can be calculated as:

If a simple transmission channel model and data source model is assumed, the BER may also be calculated analytically.

If the communication channel is of limited bandwidth, there is the possibility of interference in either DM or PCM.

If an undesired transmitter transmits on the same channel but with a different PN sequence ( or no sequence at all ), the de-spreading process results in no processing gain for that signal.

If the channel is clean enough, most of the time only one bit will change in each triple.

If the channel frequency response is flat and the shaping filter has a finite bandwidth, it is possible to communicate with no ISI at all.

If aggradation continues to occur in the main channel, this will make levee overtopping more likely again, and the levees can continue to build up.

If the channel is sensed busy before transmission then the transmission is deferred for a " random " interval.

If one has an integrity-assured way to verify a shared key over a public channel, one may engage in a Diffie-Hellman key exchange to derive a one-time shared key, and then subsequently authenticate that the keys match.

If Mausolus ' ships blocked a small channel, they could keep all enemy warships out.

If p > 1 / 2, then the receiver can swap the output ( interpret 1 when it sees 0, and vice versa ) and obtain an equivalent channel with crossover probability 1 − p ≤ 1 / 2.

If a channel is not changing with time, it does not fade and instead remains at some particular level.

If a single-path channel is being modelled, so that there is only one waveform then can be zero.

If a multipath, frequency-selective channel is being modelled so that multiple waveforms are needed, Jakes suggests that uncorrelated waveforms are given by:

If some of the luminance information arrived via the chrominance channel ( as it would have if RB signals were used instead of differential UV signals ), B & W resolution would have been compromised.

If, in the trustee's judgment, `` reasonable market conditions '' did not prevail during any given year, he was to be allowed to petition the court for an extension of time within the ten-year period.

The next traditional step then was to accept it as the authoritative textbook of the Christian faith just as one would accept a treatise on any earthly `` science '', and I submitted to its conditions according to Christ's invitation and promise that, `` If any man will do his will, he shall know of the doctrine, whether it be of God, or whether I speak of myself '' ( John 7: 17 ).

If amber is heated under the right conditions, oil of amber is produced, and in past times this was combined carefully with nitric acid to create " artificial musk " – a resin with a peculiar musky odor.

If the soil holding the plant is healthy and biologically diverse, the plant will have a higher chance of surviving stressful conditions.

If not, the system may either be rejected or accepted on conditions previously agreed between the sponsor and the manufacturer.

If a normally biennial plant is grown in extremely harsh conditions, it is likely to be treated as an annual because it will not survive the winter cold.

If a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium moves to partially reverse the change.

If conditions change, so that the pope judges it safe to make the appointment public, he may do so at any time.

If these conditions do not hold, the formula describes a more general affine transformation of the plane provided that the determinant of A is not zero.

If < math > c ^ 2 < 4km </ math > there are two complex conjugate roots a ± ib, and the solution ( with the above boundary conditions ) will look like this:

If the conditions are restored too quickly, the nucleic acid strands may realign imperfectly.

If the second electrode is also at standard conditions, then the measured cell potential is called the standard electrode potential for the electrode.

If these conditions can change, they are better represented by two predicates open ( t ) and on ( t ) that depend on time ; such predicates are called fluents.

If the lift coefficient for a wing at a specified angle of attack is known ( or estimated using a method such as thin airfoil theory ), then the lift produced for specific flow conditions can be determined using the following equation:

If a model for a language moreover satisfies a particular sentence or theory ( set of sentences satisfying special conditions ), it is called a model of the sentence or theory.

If only the second and third conditions of the definition of measure above are met, and takes on at most one of the values, then is called a signed measure.

If the first-countability axiom were imposed on the topological spaces in question, the two above conditions would be equivalent.

If the firm decides to operate, the firm will continue to produce where marginal revenue equals marginal costs because these conditions insure not only profit maximization ( loss minimization ) but also maximum contribution.

If met with ideal conditions on a new planet's surfaces, the bacteria become active and the process of evolution begins.

If there is insufficient assurance, " it will be prudent to delay baptism ", while keeping contact with the parents in the hope of securing the required conditions for celebrating the sacrament.

If the opponent in the hold begins to tap out at the same time a referee counts to three for pinning the opponent delivering the hold, both opponents have legally achieved scoring conditions simultaneously.

If the scan time was too long, the response of the PLC to process conditions would be too slow to be useful.

If an appellate court determines that reversible error occurred, it may reverse the judgment of the lower court and order a new trial on such terms and conditions as are found to be just.

If the solvent is a gas, only gases are dissolved under a given set of conditions.

At least two assumptions are necessary for the validity of the standard model: first, that supply and demand are independent ; and second, that supply is " constrained by a fixed resource "; If these conditions do not hold, then the Marshallian model cannot be sustained.
