Actually glitch results in wastage of power due to transition of low to high or high to low state. This unwanted transition occurs because we are not receiving the input signals at the gate at the same time and which results in transtion of state of te output and which is corrected when second signal arrives and we have again transtion of state and more loss of power.

Wherever there is noise at work you should be looking for alternative processes, equipment and/or working methods which would make the work quieter or mean people are exposed for shorter times. You should also keep up with what is good practice or the
New plant and workplaces. Noise control measures can be included in the design of the installation area and the design and construction of a new workplace. Where a plant is designed for a particular workplace, designers should design the plant to eliminate or control noise emissions where there is a risk to a person's hearing.
Noise can be continuous, variable, intermittent or impulsive depending on how it changes over time. Continuous noise is noise which remains constant and stable over a given time period. The noise of boilers in a power house is relatively constant and can therefore be classified as continuous. Most manufacturing noise is variable or intermittent.
A multi-exponential NMR signal may reduce the accuracy of MLE-based parameter estimation if a bad initial guess is used, but it has little effect on the suppression of random noise. Harmonic noise can reduce the effect of MLE, while impulsive noise has little effect on MLE.
Remind your designer that plants can also make white noise too, that is if you choose the right ones. Wind in pine needles produces a distinctive sound. The rustle of stiff oak leaves or that of dry autumn ones can make problem noise seem minimal. Quaking aspen and bamboo are also recommended for this.
